* fix: harden deploy/update concurrency and node-targeting safety

Release stabilization for deploy/update operational safety.

Per-stack operation locking is now global. Background lifecycle paths
(scheduler auto stop/down/start/backup/update, webhook execute, Git source
auto-deploy, image auto-update, label bulk actions, fleet snapshot redeploy,
and mesh redeploy) acquire the per-node, per-stack lock through a new
StackOpLockService.runExclusive helper and skip rather than race a manual
deploy/update/rollback/backup on the same stack and node. Skips surface
honestly (a failed scheduled run, a recorded webhook failure, a per-stack
batch result, or a thrown error) instead of a silent no-op.

Update readiness and policy-bypass now run against the node captured when the
dialog opened, not the live active node, so switching nodes while a dialog is
open cannot retarget the update or the bypass retry.

Rollback readiness no longer presents a moving-tag or unpinned image as a ready
image revert. Restoring files does not revert a moving tag, so those stacks
read as partial, and the rollback success message states that the compose and
env files were restored.

* fix: lock blueprint reconcile against manual ops and correct rollback wording

Follow-up to the deploy/update safety hardening, closing two more gaps from a
verification pass.

BlueprintService.deployLocal and withdrawLocal called ComposeService directly,
so blueprint reconciliation could race a manual deploy/update/rollback/backup on
an owned stack. Both now run their compose lifecycle call through
StackOpLockService.runExclusive and skip (recorded as a failed reconcile,
retried on the next cycle) on conflict. The withdraw holds the lock across both
the compose down and the directory delete so neither races a manual operation.

The runtime rollback messages overstated recovery: a rollback restores the
compose and env files and recreates containers, but does not revert an image
behind a moving tag. The auto-rollback deploy-progress output, the recovery
panel and chip, the failure toasts, and the manual rollback route message now
state that the compose and env files were restored, with the matching OpenAPI
example and atomic-deployments doc updated.

* fix: acquire stack lock before blueprint deploy mutates compose and marker files

Local blueprint deploy wrote the compose and marker files and ran the policy
assert before acquiring the per-stack lock; the lock only wrapped the deploy
itself. A reconcile could therefore rewrite an owned stack's files while a
manual deploy/update/rollback/backup was running. The lock now wraps the whole
critical section (create, write compose, write marker, policy assert, deploy),
so on conflict nothing is written and the reconcile records a failed outcome.

Adds a test asserting a deploy under a held lock records failed, writes no
marker file, and leaves the manual lock untouched.

* fix: make remote blueprint apply atomic under the receiving node's stack lock

Remote blueprint deploy wrote the compose and marker files to the target node
via separate HTTP calls and only locked on the final deploy, so the file writes
could race a manual operation on that node. A node's operation lock is
process-local and cannot be held by the hub across HTTP calls, so the locked
create/write/deploy now runs on the receiving node.

The locked critical section is extracted into BlueprintService.applyLocalUnderLock
and exposed via POST /api/blueprints/apply-local. The hub posts the blueprint to
that endpoint in one call; the receiving node runs create + write compose+marker
+ deploy under its own per-stack lock. Older nodes without the route answer 404
and fall back to the legacy multi-call flow. The endpoint is gated by paid tier
and the same per-stack stack:edit and stack:deploy permissions as the
PUT-compose + deploy it bundles, validates the stack name, compose size, and
marker structure, and returns 409 on a lock conflict without writing anything.

Adds tests for the atomic single-call path, the 404 legacy fallback, the 409
lock-conflict mapping, the route validation and permission paths, and the
write-compose-then-marker-then-deploy ordering of the shared locked apply.

* fix(deps): bump undici to 7.28.0 to clear high-severity advisory

The frontend CI npm audit gate (--audit-level=high) failed on a transitive
undici 7.25.0 (a dev-only dependency via jsdom): TLS certificate validation
bypass (GHSA-vmh5-mc38-953g) and cross-user cache information disclosure
(GHSA-pr7r-676h-xcf6). Bumping undici within jsdom's existing ^7.25.0 range to
7.28.0 clears the high-severity advisory and unblocks the frontend job. Lockfile
only; no direct dependency or source change.

Anso 38aabe7064 feat: health-gated updates and rollback readiness (#1354)
* feat: classify stack deploy and update failures with suggested next actions

Failed deploy and update responses now carry a failure classification
(cause category, headline, and suggested next step) derived from the
compose error output. The recovery panel and chip render the
classification and include it in copied diagnostics, and gateway-style
failures surface as a node-unreachable cause.

* feat: add update and rollback readiness reports for stacks

Before a manual update, Sencho now shows an advisory readiness verdict
computed from the stored preflight result, open drift findings, live
container health, the pending image change, the rollback backup slot,
and node disk headroom. The Stack Dossier gains a rollback readiness
section that states what a rollback can restore and explicitly
discloses that volume and bind-mounted data are not covered. Toolbar
and sidebar updates now share one update path, and admins can create a
fleet snapshot from the readiness dialog before updating. Nodes that do
not advertise the capability keep the direct update flow.

* feat: observe stack health after updates with a post-deploy health gate

After a deploy or update succeeds, Sencho now watches the stack for a
configurable observation window and records a passed, failed, or
unknown verdict: containers must stay running, healthchecks must report
healthy, and restart loops or disappearing containers fail the gate.
The deploy panel shows the observation live and holds off auto-closing
until the verdict lands, a failed gate surfaces the existing recovery
actions including rollback, and the stack timeline records update
started and gate verdict events. Scheduled, webhook, bulk, and
git-source updates are gated the same way; rollbacks and installs are
deliberately not. The gate is observational only and can be tuned or
disabled per node under host alert settings.

* docs: document health-gated updates and rollback readiness

New operator page covering the update readiness dialog, the post-update
health gate and its settings, the rollback readiness disclosure, and
classified failures, with cross-links from the atomic deployments and
deploy progress pages. The API reference gains the readiness and
health-gate endpoints, the healthGateId success field, and the failure
classification schema on deploy and update error responses.

* feat: withhold the success verdict while the health gate observes

An update used to show a green Succeeded that a failed health gate then
contradicted moments later. The deploy modal now reports Verifying
health while the gate observes, shows success only when the gate
passes, and makes a failed or unknown gate the headline result; success
toasts soften to a verifying message while a gate runs. The mobile
recovery card groups its actions behind one bottom-right Take action
menu so it stays compact on a phone, with the classified cause still
visible on the card. A successful image update now also counts as the
last known-good marker in rollback readiness, and the docs gain
screenshots of the readiness dialog, gate states, dossier section, and
settings.

* fix: harden log format strings and the env existence path check

Log calls that interpolated the stack name into the console format
string now use constant format strings with placeholder arguments, and
envExists validates path containment inline at its filesystem access,
matching the established patterns used elsewhere in the same files.

* test: adapt deploy modal success specs to the post-deploy health gate

The deploy feedback modal now withholds its success verdict while the
health gate observes the new containers, showing "Verifying health"
until the gate passes. The two success-path E2E tests waited for
"Succeeded" within the gate's 90s default window and timed out.

Shorten the observation window to the 15s minimum for these tests via
the settings API, assert the verify-then-succeed sequence the modal
actually renders, and restore the default window afterward so the test
value does not leak into later runs.

* fix: serialize health gate polling and harden gate observation

Address race conditions in the post-update health gate found in review.

Backend: the gate poller used setInterval, so a Docker observe slower
than the 5s tick could overlap the next poll and corrupt the restart and
missing-container accounting, and a wedged socket could leave a poll
pending forever. Polling is now single-flight: each cycle self-schedules
the next only after it settles, and the observe is bounded by an 8s
timeout so a hung probe counts as a poll error and resolves the gate
unknown after three in a row.

Frontend: the gate poller could overlap requests, letting a slow earlier
"observing" response overwrite an already-applied terminal verdict. It is
now single-flight with a terminal latch, so a late response can never
roll the UI back from passed or failed.

Also reject a non-digit nodeId on the snapshot coverage route instead of
letting parseInt coerce it, document that turning off the deploy progress
panel opts out of the live gate UI while the gate still runs server-side,
and add gate-coverage tests for the webhook, git source, and auto-update
apply paths plus the new single-flight, observe-timeout, and recovery
cases.
