Summary

Adds an honest release workflow accounting document covering the current skill,
script, workflow, and agent breakdown for github-workflows, then links it from
the README.

Refreshes the document after the Release Commander freshness review:

• Package scripts now include agent:close-preflight, agent:pr-ready,
  pr:contract, and test.
• Workflow inventory now reflects 16 reusable workflows plus direct
  self-test.yml.
• Obsolete CodeQL planned-work references were removed after ci(codeql): remove reusable workflow #43.
• Lifecycle gaps are qualified after archon-setup fix(repo-required-gate): exempt dependabot from the PR body/title contract #94: ecosystem setup can
  install/audit the repo-template agent lifecycle baseline, while this repo
  still lacks local repo-specific lifecycle commands beyond PR contract
  wrappers.

Closes #34

Scope

• In scope: document current actual workflow, expected workflow, planned gaps,
  and role/script ownership.
• Out of scope: implementing missing agent lifecycle scripts, changing workflow
  gates, changing branch protection, or merging this PR.

Verification

• git diff --check

  command: git diff --check

  result: pass; exited 0 with Git line-ending normalization warning for docs/release-workflow-breakdown.md only

Verification Notes

Branch refreshed by rebasing onto origin/main at 9975cfd; pushed head is
533d686.

Release Commander freshness findings were addressed in
docs/release-workflow-breakdown.md.

GitHub CI note: no PR checks are reported by design for this docs-only diff
(README.md and docs/release-workflow-breakdown.md). The repo's direct
self-test.yml workflow is path-filtered to scripts/package/self-test workflow
changes, and the other repo workflow files are reusable workflow_call workflows
that run only when called by consumers.

Docs / Changelog

• Docs updated in docs/release-workflow-breakdown.md.
• README link text was already adequate; no README refresh was needed beyond the
  original link addition in this PR.
• Changelog fragment not added because this is docs-only workflow accounting.

Risks

• Risk level: low.
• Rollback: revert the docs commits.
• Remaining freshness concern: HANDOFF.md remains stale and still reports the
  older workflow count; this PR documents that gap instead of changing handoff.
