feat(lint): expand Vale audit prefilter into a broader plugin-content harness

Deferred item from PR #85 review. Per ADR-0013: cherry-picks two low-noise
rules from trialing write-good/alex against the real corpus (VagueQualifier,
SentenceOpenerThereIs) into styles/Kyberforge rather than adopting either
package wholesale (both are tuned for blog prose and were noisy on this
repo's terse, imperative instruction files - see the ADR's rejected-rule
list). Adds a new skill-size-check pre-commit hook enforcing agentskills.io's
500-line/5,000-token SKILL.md ceiling, currently unenforced. Fixes the 28
resulting violations across 20 existing SKILL.md/agent files so the
enforcing pre-commit hook lands clean.

governance.md/CONTROLS.md were evaluated and excluded as rule sources -
they're org/CI-infrastructure controls, not prose patterns Vale can express.

 - **`delete_release` takes a numeric `id`, never a tag name.** `delete_tag` is the mirror opposite — it takes the `tag_name` string, never a numeric id. These two tools are asymmetric on purpose; passing a tag name to `delete_release` or a numeric id to `delete_tag` fails. Always resolve the numeric release id via `list_releases` or `get_release` first if you only have a tag name in hand.
 - **Deleting a release does not delete its tag.** They are separate destructive operations against separate resources — a release is a wrapper (title, notes, draft/prerelease flags, assets) around a tag, not the tag itself. If the intent is to remove both, call `delete_release` and `delete_tag` separately.
-- **`list_releases`/`list_tags` default to `per_page: 20`**, unlike most other gitea-mcp tools which default to 30. There is no auto-pagination in the MCP layer — to get a complete result set, loop `page` upward until a page returns fewer than `per_page` results.

 - **`is_draft`/`is_pre_release` are explicit booleans the caller sets on `create_release` — never inferred from `tag_name`.** Note the input param is `is_draft`, which maps to the `draft` field on the *response* object (see Dispatch table below and `references/call-signatures.md`) — `draft` is never a valid input key. Practitioner convention (per the `tea` CLI) uses `-beta`/`-rc` suffixes for prereleases (e.g. `v2.0.0-beta.1`), but Gitea does not enforce or infer this from the tag string. If the user names a tag that looks like a prerelease, set `is_pre_release: true` explicitly rather than assuming the flag is redundant with the name.
 - **Tag names are conventionally semver, `v`-prefixed** (`v1.2.0`, `v2.0.0-beta.1`), but this is a practitioner convention, not a Gitea constraint — don't reject or rewrite a caller-supplied tag name that doesn't follow it.

 - [ ] **Creating a release:** Call `create_release` directly with `tag_name` + `target` + `title` — Gitea is assumed to create the underlying tag automatically if `tag_name` doesn't already exist (this is plausible behavior inferred from the API shape, not directly confirmed in the research docs), so a separate `create_tag` call is only needed when you want to tag a commit without wrapping it in a release yet. Verify the tag exists afterward if this matters to the caller. Set `is_pre_release`/`is_draft` explicitly per the Gotchas above; don't leave them to default inference.
 - [ ] **Deleting a release safely:** Resolve the numeric id first — call `list_releases` (paginate if needed, see Gotchas) or `get_release` if the id is already known, find the entry matching the target `tag_name`, then call `delete_release` with that `id`. Never pass `tag_name` to `delete_release`.
 - [ ] **Deleting a tag along with its release:** Delete the release first (frees the id lookup), then call `delete_tag` with the `tag_name` separately — confirm both are intended before proceeding, since each is an independent irreversible operation.
