ci(lint): pin the released-analyzer contract to zsh-lint v1.5.0

[ss-o]

Moves the Released Analyzer Contract job in zsh-lint-test.yml from zsh-lint v1.4.0 to v1.5.0, and updates the knowledge source knowledge/domains/ci/zsh-lint-ci.md and its generated runbooks/zsh-lint-ci.md to name v1.5.0.

Part of z-shell/zsh-lint#612. zsh-lint v1.5.0: https://github.com/z-shell/zsh-lint/releases/tag/v1.5.0 (signed tag on b3b9fdc). The parser fork is now part of the analyzer's root module and the analyzer needs Go 1.27; the reusable workflow already builds ./cmd/zsh-lint from the checkout root and reads Go from the analyzer's go.mod, so it needs no change.

Verification

• v1.5.0 built from the tag the way the reusable workflow builds it, then automation/ci/zsh_lint_ci.py --mode strict on automation/ci/fixtures/zsh-lint/clean.txt exits 0 and writes the full report.
• python3 -m unittest automation/ci/test_zsh_lint_ci.py passes (13 tests).
• knowledge-delivery.py --check (57 consumers), knowledge-coverage.py, validate-agent-policy.py, org-routing.py validate, git diff --check and trunk check --no-fix --ci on the three files pass.

This repository's Renovate preset would repin only the workflow; this change keeps the documented version in step with it.

Findings

No actionable findings. The three one-line changes move the Released Analyzer Contract job's zsh-lint-ref from v1.4.0 (aff6018) to v1.5.0 (b3b9fdc) and name v1.5.0 in the knowledge source and its generated runbook, which stay byte-consistent (knowledge-delivery.py --check passes).

Checklist verdicts

• Pin: pass. b3b9fdce3799827755ae546d2185e3d85063e6db is the commit the signed v1.5.0 tag points to. The reusable workflow builds ./cmd/zsh-lint from the checkout root and reads Go from the analyzer's go.mod, which matches v1.5.0's root-module layout and Go 1.27.
• Behavior: pass. v1.5.0 built the way the workflow builds it passes zsh_lint_ci.py --mode strict on the clean fixture, and the 13 test_zsh_lint_ci.py tests pass. The hosted Released Analyzer Contract / Zsh Lint job, which runs the reusable workflow with v1.5.0, also passes on this head.
• Checks: pass. Coverage, agent policy, routing validation, whitespace and Trunk pass locally; all 14 hosted checks pass; the commit signature is verified.
