fix(lint): resolve audit findings on vale skills

Merge duplicate gotcha in vale-config (Packages vs BasedOnStyles was
stated twice) and align vale-run's category field with vale-config's
(lint, not linting) so sibling skills in the plugin agree.

 - Installing the `vale` binary installs no styles. A fresh `.vale.ini` with `BasedOnStyles` set will fail or find nothing until `vale sync` runs and downloads the `Packages` it declares.
 - `.vale.ini` is order-sensitive: global (core) settings first, then the optional `[formats]` section, then glob sections (`[*]`, `[*.md]`, …). Settings in a glob section only apply to files matching that glob.
-- Declaring `StylesPath` and `Packages` alone activates nothing. A style only lints files once it's listed in `BasedOnStyles` under a glob section that matches those files — this is the step people forget.
-- `Packages` (top-level, for `vale sync` to fetch) and `BasedOnStyles` (per-glob, to activate) are two different keys serving two different purposes. Both are required for a third-party style to actually run.
+- `Packages` (top-level, fetched by `vale sync`) and `BasedOnStyles` (per-glob, activates) are separate keys — a style only lints files once it's in both. This is the step people forget.
