* chore(ci): bump Node 20 actions to Node 24 ahead of June 2026 deadline (TASK-1165)

GitHub deprecated Node 20 in Actions runners; the hard cutoff is
June 2nd, 2026. Pre-emptively bumps the three remaining Node 20
holdouts to their latest Node 24 versions, SHA-pinned per the
existing convention:

- actions/setup-node v4.4.0 → v6.4.0 (using: node24)
- actions/upload-artifact v4.6.2 → v7.0.1 (using: node24)
- anchore/sbom-action/download-syft v0.18.0 → v0.24.0 (using: node24)

Breaking-change review (all clear for our usage):

- setup-node v5/v6: only behavioral change is "limit automatic caching
  to npm" — we already pass cache: "npm" explicitly. node-version: "24"
  + cache-dependency-path: web/package-lock.json continue to work.
- upload-artifact v5/v6: v5 treats the Node 24 bump as breaking; v6
  requires Actions Runner ≥ 2.327.1 (GitHub-hosted runners are
  auto-updated, so no concern). Our single-fixed-name failure-only
  upload is unaffected.
- upload-artifact v7: adds optional archive: false single-file unzipped
  uploads + ESM internals. Our usage (name/path/retention-days) is
  unchanged.
- sbom-action 0.18→0.24: minor 0.x bumps; v0.24 release notes
  explicitly cite "update to node 24 + deps".

Post-audit: every uses: spec in .github/workflows/ now reports
node24 or composite. No Node 20 actions remain.

Per TASK-1165 verification: this PR touches .github/workflows/release.yml,
so the playbook's RC decision rule (PLAYB-1160 step 1) triggers — the
next release will warrant a vX.Y.Z-rc.1 to confirm the deprecation
annotation is gone before shipping stable.

* chore(ci): cap golangci-lint cache to 1 day to avoid poisoning recurrences (BUG-1624)

PR #635's first CI run failed on 30+ SA5011/SA4023 false positives
against unchanged code; local cold-cache lint reported 0 issues.
Diagnosis: golangci-lint-action's cache stores the prior pass's
resolved issue list, and once a pass writes degenerate results
(analyzer upgrade, plugin reset, sub-package drift), every downstream
restore replays that list verbatim until the cache key rotates.

The cache key hashes go.mod/go.sum/.golangci.yml plus an action-internal
prefix, so in steady state the key is stable for days and the
poisoned content propagates across PRs. Default invalidation is 7 days.

This change cuts it to 1 day. Most runs still hit warm cache (lint
runs back-to-back within hours of each other are common); we
guarantee a daily fresh full pass that overwrites any bad cached
state. Estimated cost: ~30-60s extra on one CI run per day.

Hand-mitigated the immediate occurrence by deleting the two poisoned
cache entries via the GH cache API; rerun then went green. BUG-1624
captures the full diagnosis + alternatives considered.

* chore(ci): cache Playwright browsers to dodge CDN slow-paths (BUG-1625)

PR #635 hit two consecutive 10-minute timeouts on the E2E job, both
dying inside `npx playwright install --with-deps chromium` while
downloading Chrome from cdn.playwright.dev. The apt portion completed
in ~10s; the CDN download hung for ~7 minutes before the
`timeout-minutes: 10` ceiling killed the job.

Same code earlier in the day ran E2E green in 1m07s — it's a CDN
slowness event, not a behavioral regression. But two-runs-in-a-row
timeouts mean the steady state is fragile.

Fix: cache `~/.cache/ms-playwright` per resolved @playwright/test
version. Splits the install step in two:

- Cache miss: `npx playwright install --with-deps chromium` — full
  apt + browser download (current behavior).
- Cache hit:  `npx playwright install-deps chromium` — apt system
  libraries only (~10s); browser binary is already on disk.

Cache key reads the resolved version from package-lock.json so a
Playwright bump auto-invalidates. Pinned to actions/cache v5.0.5
(node24) per the workflow's SHA-pinning convention.

After the first warm run on each Playwright version, the CDN is
out of the critical path; an outage there can only burn one CI run
before steady state recovers. BUG-1625 has the full diagnosis.
