Add /pre-release slash command and extend /pre-commit

[nanotaboada]

Problem

There is no /pre-release slash command for this repo. The release process (determining the next version and club codename, preparing the release branch, updating CHANGELOG.md, tagging) is done manually and is error-prone.

Additionally, step 1 of /pre-commit currently reads:

"Remind me to update CHANGELOG.md [Unreleased] section (Added / Changed / Fixed / Removed) — I must do this manually."

The agent should handle this step, not defer it to the user. A CodeRabbit review step is also missing from the pre-commit flow.

Proposed Solution

1. Rename .claude/commands/precommit.md to .claude/commands/pre-commit.md.

2. Update step 1 of .claude/commands/pre-commit.md to:

   Update CHANGELOG.md [Unreleased] section — add an entry under the appropriate subsection (Added / Changed / Fixed / Removed) describing the changes made, referencing the issue number.

3. Add a CodeRabbit review step to .claude/commands/pre-commit.md after all checks pass: run coderabbit review --type uncommitted --prompt-only.

   • If actionable/serious findings are reported, stop and address them before proposing the commit.
   • If only nitpick-level findings, report them and continue to the commit proposal.
   • Skip gracefully with a note if the CodeRabbit CLI is not installed.

4. Add .claude/commands/pre-release.md implementing a three-phase pre-release checklist:

   • Phase 1 — Determine next release: verify clean master, read the historic football club naming convention from CHANGELOG.md (A–Z table), run git tag --sort=-v:refname, infer the version bump from [Unreleased], and present a summary for confirmation before proceeding.
   • Phase 2 — Prepare release branch: create release/vX.Y.Z-{club}, move [Unreleased] content into a versioned heading, propose the docs(changelog) commit, then run /pre-commit and open a PR — all with explicit confirmation at each step.
   • Phase 3 — Tag and release: wait for CI green and PR merged into master; pull master; propose the annotated tag; push only after explicit approval.

Acceptance Criteria

• .claude/commands/precommit.md renamed to pre-commit.md
• Step 1 of /pre-commit updates CHANGELOG.md automatically, referencing the issue number
• /pre-commit runs coderabbit review --type uncommitted --prompt-only after checks pass; blocks on serious findings, continues on nitpicks
• /pre-release is available and follows the propose-before-acting workflow
• Correctly reads the club naming convention from CHANGELOG.md
• Infers the correct version bump from [Unreleased] content
