rename: Codename 206 -> Bari 206

Retires the working codename now rather than at 1.0, because the two identity
constants a DAW uses to recognise a plugin across sessions can only be changed
for free while nothing has saved a project with it. Verified: zero references
to the plugin across all 69 FL project backups, under any identity string.

Derived spellings:
    Cargo package     codename_206        -> bari_206
    bundle / DAW name Codename 206 |
                      206 prototype       -> Bari 206      (unified; drops "prototype")
    Rust types        Codename206(Params) -> Bari206(Params)
    CLAP_ID           com.mikkeli.codename-206
                                          -> org.novoyuuparosk.bari-206
    VST3_CLASS_ID     Codename206Maxi!    -> Bari206Multiband

CLAP_ID moves to reverse-DNS on a domain actually controlled, and stops
disagreeing with a VENDOR that was already Novoyuuparosk. VST3_CLASS_ID stays
exactly 16 bytes and drops "Maxi", which sat close to Image-Line's Maximus and
Maximizer in the same product category.

Author identity converges on Mikkeli Matlock <mikkeli@novoyuuparosk.org>;
Cargo authors had been carrying a personal gmail address while Plugin::EMAIL
already used the org one. VENDOR stays Novoyuuparosk, which is the org rather
than the person, and copyright stays with the person.

Deliberately unchanged: the repo, its remote, the local directory and the
homepage URL all keep "codename-206". Renaming those buys nothing and costs a
Gitea rename, a remote rewrite and a directory move, so the bare "codename-206"
is current branding rather than residue - and is the one spelling the STALE
list must not contain.

Driven by check-branding.sh rather than by grep: setting the canonical block
listed all 26 sites, including .github/workflows/ci.yaml, which no explicit
check covered. That gap is now closed by a positive check on the CI bundle
command, so a future rename fails in seconds instead of after a full compile.
STALE now carries both the retired and the new spellings, so the next rename
is self-checking too.
