shankar0123 0157510d48 ci-pipeline-cleanup Phase 5+6: collapse vendor matrix; delete Windows matrix
Bundle: ci-pipeline-cleanup, Phases 5+6 / frozen decisions 0.4 + 0.5
+ 0.6. Revises Bundle II decisions 0.4 (Windows matrix) and 0.9 (per-
vendor granularity).

PHASE 5 — Linux vendor matrix collapsed (12 jobs → 1):

The previous per-vendor matrix produced 12 status-check rows for
~1 real assertion (115/116 vendor-edge tests are t.Log placeholders
per Bundle II Phase 2-13 design). Granularity was fake signal.

Single-job version: brings up all 11 sidecars at once via
docker compose --profile deploy-e2e up -d, runs go test -run
'VendorEdge_' once, tears down once.

Critical caveat: requireSidecar() in deploy/test/vendor_e2e_helpers.go
uses t.Skipf() when a sidecar isn't reachable — silent test skip,
not CI failure. The new Skip-count enforcement step
(scripts/ci-guards/vendor-e2e-skip-check.sh) counts SKIP lines and
fails the build if it exceeds the allowlist at
scripts/ci-guards/vendor-e2e-skip-allowlist.txt (15 windows-iis-
requiring tests legitimately skip on Linux per Phase 6).

PHASE 6 — Windows matrix deleted entirely:

The deploy-vendor-e2e-windows job removed. Two reasons:
1. Can't physically work on windows-latest today (Docker not started
   in Windows-containers mode by default; bridge network driver
   missing on Windows Docker — see CI run 25183374742 failure logs).
2. Even fixed, validates nothing — all 16 IIS + WinCertStore tests
   are t.Log placeholders that exercise no IIS-specific behavior.

Per Bundle II frozen decision 0.14, the third criterion for
"verified" status in the vendor matrix is operator manual smoke
against a real instance. IIS + WinCertStore now satisfy that via
the playbook (Phase 6 follow-up adds docs/connector-iis.md::
Operator validation playbook).

The windows-iis-test sidecar STAYS in deploy/docker-compose.test.yml
under profiles: [deploy-e2e-windows] for operator local use. Linux
CI never activates this profile.

Operator-required action before merge: RAM headroom verification on
prototype branch (per frozen decision 0.14). If peak RSS > 12 GB on
ubuntu-latest with all 11 sidecars up, fall back to bucketed matrix
per cowork/ci-pipeline-cleanup/decisions-revised.md.

ci.yml: 417 → 383 lines (-34 net; -1105 cumulative since baseline 1488).
Status checks per push: 19 → 7 (collapse 12 vendor + 2 windows = -14;
add image-and-supply-chain in Phase 7-9 = +1; net 19-12-2+1 = ~7).

Operator action for Phase 13: update GitHub branch protection rules
(required-checks list 19 → 7 entries). Documented in cowork/
ci-pipeline-cleanup/decisions-revised.md.
