refactor(skills)!: rename kvb-git-changelog to kvb-release-changelog

A new release category groups what announces a release (changelog,
article, posts); the changelog skill is its first member. The naming
test lists the category and the README organigram places the skill
under it.

BREAKING CHANGE: /kvb-git-changelog is now /kvb-release-changelog;
make install replaces the installed copy, kvb-skill-cleanup removes the
legacy directory.

Evidence: make test green, ruff and markdownlint clean
(/tmp/rename-changelog-make-test-2.log); no reference to the old name
left in the tree; MEDUSA 5 files, 0 findings.

🎯 Fix: 97 %
💥 Break: 3 %
💸 Cost: 100 %
⏱️ Time: –
🛡️ Security: 100 %
🏆 Score: 94
🚦 Gate: ✅ 90/5, cost and time <= 100, security 100 %

 ## Naming 🏷️
 
-Every first-party skill is named `kvb-<category>-<name>` with one of these categories: `think`, `create`, `code`, `ci`, `git`, `check`, `org`, `agent`, `skill`, `coach`: `think` thinks without producing a file, `create` produces an artifact, `code` works on code, `ci` on pipelines, `git` on history and forges, `check` analyses and reports findings, `org` coordinates agents, `agent` acts on one agent itself: its repository setup (code index, agent instructions) and its state (relax, sleep, wake up), `skill` works on skills themselves, `coach` serves the operator's wellbeing. Only `kvb-cleanup`, `kvb-coach`, `kvb-help` and the collectors `kvb-dream`, `kvb-optimize` and `kvb-transcend` stand without a category. Names use `a-z`, `0-9` and single hyphens, at most 64 characters, and equal their directory name. `tests/test_naming.py` enforces all of it, including that the organigram below lists every skill under its category.
