feat: sync branding checker from nih-plug-template

The template grew a considerably more thorough version of the checker this
repo seeded: vendor/email/homepage/description coverage, Rust type names,
CLAP_ID reverse-DNS validation, opt_check so a missing file skips instead
of failing, a git/find fallback so the stale scan cannot pass vacuously
outside a checkout, and a TODO scaffolding report. Take that body verbatim
rather than let two copies drift; fixes belong in the template first.

Three adaptations, all structural rather than stylistic:
- params structs live in src/params.rs here, not src/lib.rs
- CLAP_DESCRIPTION wraps onto a second line, so the const name and its
  value never share one line; match the value alone
- STALE is seeded with this repo's CURRENT spellings. Each is skipped
  while still canonical and arms the moment that value changes, so the
  planned "codename 206" -> "206" rename checks itself: every spelling
  left behind becomes a FAIL naming the files that still hold it.

28 passed, 0 failed, 8 skipped. Verified against drift, not just for a
green run: wrong params name, wrong CLAP_DESCRIPTION, and a simulated
rename each fail with exit 1.

# check-branding.sh - verify the plugin's branding/identity strings agree everywhere.

# Plugin branding is duplicated across the build manifest, the bundler manifest,
# the deploy script and the source. Nothing makes them agree, so a rename drifts
# silently: the bundle builds under one name and the deploy script looks for
# another. This asserts they match, and that the identity constants are legal.
