feat(kvb-release): release brief method with article and post channels

kvb-release listens once, writes one brief since the previous tag and hands each channel its slice; kvb-release-article writes the long form and kvb-release-post the short posts, each listening before it brainstorms. A project's own release skill sets file names, title and post structure, and an empty channel list means every channel the project covers. kvb-release-changelog moves its lint steps into lint.md.

 ## Naming 🏷️
 
-Every first-party skill is named `kvb-<category>-<name>` with one of these categories: `think`, `create`, `code`, `ci`, `git`, `release`, `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, `release` announces a release (changelog, article, posts), `check` analyses and reports findings, `org` coordinates agents, `agent` acts on one agent itself: its repository setup (code index, agent instructions) and its state (drain, suspend, resume), `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.
