release: prepare v1.4.0 and finish review execution fixes

[MisterWanted]

Summary

• Prepare v1.4.0 after landing the dependency update, workspace dashboard, request-local tool-name codec and isolated client artifacts (chore(gui): consolidate Dependabot updates and lockfile #203, feat(gui): migrate workspace controls and remove template UI patterns #197, fix(adapters): preserve long tool names across Chat Completions #195, feat: add deterministic isolated OCX client artifacts #193).
• Make external review advisory while retaining exact-head technical checks, substantive security analysis and actual repository permissions. Valid in-scope findings mean repair and verification; explicit read-only work remains read-only.
• Fix temporary startup port probes hanging on accepted scanner sockets, cover both probe paths with a deterministic regression, and reap only owned test process groups after failed launcher fixtures.
• Keep discovery GET/HEAD requests out of image-relay fixture counts. Document explicit port pinning and scanner handling. Repository pre-commit formatting accounts for the larger test/documentation diff.

Test plan

• Full normal prepush: typecheck, GUI lint, complete isolated runtime suite and privacy scan passed; no hooks skipped.
• Image-relay regression demonstrated failing before its fix; 121 focused image/combo/policy tests passed.
• Port-probe regression demonstrated failing before its fix; 33 focused port/reclaim/launcher tests and typecheck passed.
• Documentation build: 156 pages passed.
• After merge: require CI and Service lifecycle on the exact merged SHA, publish through release.yml, deploy the immutable GHCR digest, verify health version/gitSha, and run the tagged full OS matrix.

Security analysis

Only connections accepted by the owned temporary availability probes are destroyed. Foreign listeners, PID allowlists, authentication, credentials and deployment permissions are unchanged. External approval is not represented as independent verification. Full technical/security checks remain required.

This release-preparation PR follows the current main-only MAINTAINERS policy and executable target gate.

Summary by CodeRabbit

• New Features

  • Updated the CLI documentation to explain explicit port pinning and temporary port availability checks.
  • Updated the package version to 1.4.0.

• Bug Fixes

📝 Walkthrough

Walkthrough

The pull request updates repository execution policies, fixes accepted port-probe cleanup, adds regression coverage, updates CLI documentation and package metadata, isolates image discovery probes in tests, and improves launcher test process cleanup.

Changes

Execution policy

Layer / File(s)	Summary
Policy wording and validation AGENTS.md, MAINTAINERS.md, tests/review-execution-policy.test.ts	External approval is advisory. Required technical checks remain mandatory. Authorized in-scope findings require repair and verification. Security-boundary changes require recorded security analysis. Tests assert the policy wording.

Port probe lifecycle

Layer / File(s)	Summary
Probe connection cleanup and regression coverage src/server/ports.ts, tests/ports.test.ts	Temporary listeners destroy accepted probe connections before closing. Tests reproduce the accepted-socket timing case for isPortAvailable and findAvailablePort.
Port behavior documentation and release metadata docs-site/src/content/docs/reference/cli.md, package.json	The CLI reference documents pinned-port failure and immediate probe closure. The package version changes to 1.4.0.

Test harness maintenance

Layer / File(s)	Summary
Image relay test probe handling tests/server-images.test.ts	The fake image upstream rejects non-POST discovery probes without capturing them. Existing relay tests receive formatting-only changes.
Launcher process cleanup and diagnostics tests/shutdown-launcher.test.ts	The launcher test captures recent startup output and kills the complete detached process group during cleanup.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🔵 Low · up to cc5f8

This release improves port-probe cleanup and related documentation, but the CLI reference table can hide command details and the policy test should protect exact-head verification wording. Addressing these small documentation and coverage issues will make the change ready to merge.

internal pipe-separated subcommands with comma-separated code spans, preserving
all listed command details.

- Around line 15-17: Update the policy assertions in the review-execution policy
test to verify the exact-head required technical-check requirement from
MAINTAINERS.md and the no-branch-protection-bypass requirement from AGENTS.md,
while preserving the existing generic checks. Use the policy-loading or
