Adds clusterAssigner.excludeAssignees (list, default []). When non-empty, the cluster-assigner CronJob gets EXCLUDE_ASSIGNEES set to the entries comma-joined. An empty list renders no env entry at all, so existing installs render byte-identically apart from the helm.sh/chart label. Chart 0.13.0 → 0.14.0.

Why: releaser tasks must stay off sun until the releaser's PR-fallback fix ships, and the assigner's only switch for that is EXCLUDE_ASSIGNEES (agent-cluster-assigner v0.2.0).

Verified on host: 9/9 checks pass — disabled unchanged, empty list unchanged and no env entry, one entry, two entries joined, helm lint both ways, chart version, CHANGELOG placement. make precommit green.

The dark-factory run reported failed only on the container's Go 1.27.2 govulncheck GO-2026-6809 (stdlib crypto/x509, fixed in 1.27.3); host precommit on Go 1.27.3 passes. Its stray mocks/mocks.go edit was reverted.

I've completed the review. Verifying the last mechanical details confirmed: no tag on the PR head (so git-commit/feature-branch-no-tag passes), the render test is wired into make test, and the CHANGELOG entry sits correctly under ## Unreleased.

Review summary (selector mode):

Candidates: 6 rules matched by the Step 4b-i glob filter
Applicable: 3 rules selected
Skipped:

• go-security/resource-ownership → no Go handler/service method in diff
• go-security/tenant-isolation → no Go handler/service method in diff
• markdown-todo/lowercase-x-for-complete → no markdown checkbox bullets added

Must Fix (Critical): None. Mechanical funnel reported 0 findings; no Go source changed.

Should Fix (Important):

• hack/test-helm-render.sh:170 — only the empty-list and two-element cases are covered; no single-element case, no absent-key case, no assertion that the empty render is otherwise identical, and nothing pins the new v0.2.0 default.

Nice to Have (Optional):

• helm/templates/cluster-assigner-cronjob.yaml:84 — comma-joined values are ambiguous (an assignee containing a comma re-splits; a list entry that is the empty string renders EXCLUDE_ASSIGNEES as "").

Notes: 1 file (prompts/completed/245-...md) excluded by .reviewignore. precommit skipped (selector mode) — CI covers lint+test. The PR body's "0.13.0→0.14.0 / byte-identical" description is stale versus the shipped 0.14.1→0.15.0 plus default image-tag bump; the CHANGELOG itself is accurate. The HEAD commit subject is 84 chars (SHOULD-tier git-commit/subject-under-50-chars), but merge/long scoped subjects are the repo norm and the funnel did not flag it.
