fix(locale): tighten parity gate and correct copy-source wording

Address the three open review threads on the dictionary parity gate.

Regex/TEXT: localeOf now requires an uppercase ASCII [A-Z] flat-letter at
the third position of a name-prefix shape, so zh2Foo/zh_probe are no longer
treated as dictionaries in localeOf while the admission pre-filter skips
them. The two now agree exactly.

register detection now also admits a bare register identifier callee in
addition to a property access, covering a future destructured
register(NS, 'zh'|'en', dict) call instead of silently dropping it.

A 3-arg register whose dictionary argument is a local variable is resolved
through module-scope const initializers; one that cannot be resolved to an
object literal makes the gate refuse with a named error rather than skipping
the registration and narrowing the sweep.

Also restate the FALLBACK_LOCALE rationale: the residual case points at
English because a browser naming neither shipped language is the reader
least likely to read Chinese, not because English is the copy's source
language (Chinese is; packages/client/AGENTS.md). Sync the identical claim
in the bilingual Agent Note and re-record its .i18n.yaml pairing.
