gen-tm: extend the repo-key naming CONSTRAINT to the ECMAScript family

Applies the `canonicalRepoNames` 限制器 (already done for source.ts) to
javascript / javascriptreact / typescriptreact, so each emits the OFFICIAL VS
Code repository KEY NAMES natively for every construct Monogram genuinely has —
the same drop-in property source.ts gained, now across the family.

Structure mirrors the rule-sharing (javascript.ts owns the ECMAScript vocab, so
it owns the shared canonical names):
  - javascript.ts: NEW exported `jsBaseCanonical` — the shared half. 1:1 renames
    (type←type-inner, qstring-double/single←string-double/single, punctuation-
    comma/-semicolon/-accessor←scope-punctuation-*, regex←regex-literal,
    new-expr←new-expression, parameter-name←declaration-param-name,
    directives←tripleslash, this-/super-literal←scope-variable-language-this/super)
    + union wrappers (comment, string, boolean-literal, numeric-literal).
  - typescript.ts: imports + spreads `jsBaseCanonical`, keeps ONLY the TS-only
    type layer (type-parameters, type-alias-declaration, type-object, cast,
    parameter-type-annotation, type-predicate-operator, return-type). The inline
    14-entry map is gone — no duplication. Side benefit: TS picks up 7 shared keys
    it never mapped (punctuation-semicolon/-accessor, this-/super-literal, string,
    boolean-/numeric-literal), 34→41.
  - javascriptreact.ts: `withJsx` already spreads `...base`, so both .jsx and .tsx
    inherit their base map; merge a JSX delta `{ ...base.canonicalRepoNames,
    ...JSX_CANONICAL }` with the one genuine JSX 1:1 (jsx-entities←jsx-entity).
    typescriptreact.ts unchanged (pure inheritance).

Stays agnostic: the names are DATA in the grammar defs (which may know their
language, like the scopes map); gen-tm only looks up + substitutes (agnostic 8/8).
RENAME-only ⇒ tokenization byte-identical — direct old-vs-new scope-array diff
over a rich corpus (strings/comments/jsdoc/triple-slash/all number bases/this/
super/semicolons/member-access/optional-chaining/new/params/types/jsx/entities/
regex) = 0 diffs on all 4 grammars; test-issues 350/0, tsx-highlight 56/56,
highlight-bench held, js-highlight-bench 93.0%, vue-issues 20/20, tsc clean,
deterministic, zero dangling refs.

repo-compat: js 8.8→18.8%, jsx 10.6→21.3%, tsx 22.5→27.5%, ts 23.3→28.1%
(all NATIVE names, public-#include subset still 100%).

HTML audited too (separate agent): `tag` is a name-agnostic single rule spanning
the official's tags-valid ∪ tags-invalid, math/svg/doctype/cdata aren't modeled
(well-formed subset) — no genuine 1:1, so html.ts is intentionally left at its 3
already-matching keys (honest 25%, not an inflated rename).
