TextMate fidelity: fix operator longest-match, split relational, scope enum members

Three exact-scope drop-in gaps surfaced by scope-coverage's new family-only dump,
two of them real tokenization bugs the family-level bench could not see (comparison
and assignment share the `keyword` family):

1. operator-overrides was emitted as `(group1_all)|(group2_all)|…`, one alternation
   per scope group. A regex alternation is ordered-first-match, not longest-match, so
   a short operator in an earlier group shadowed a longer one in a later group: `=`
   (assignment) matched the first character of `===` (comparison), tokenizing `===`
   as three `=`. Rebuilt as ONE global length-descending alternation with a capture
   per operator → `===` before `=`, `**=` before `**` before `*`, across all groups.

2. `< > <= >=` are RELATIONAL, not comparison (the convention the official grammar
   uses; `== != === !==` stay comparison). `<=`/`>=` had no scope override at all and
   fell to the bare `keyword.operator` catch-all. Added a `keyword.operator.relational`
   group (js/ts/tsx) and renamed the bare-`<>` fallback + the multiline-generic `>`
   end-capture to it. Driven by the grammar scope map — no hardcoded operator list in
   the generator.

3. enum members now scope `variable.other.enummember` (the convention paralleling the
   `storage.type.enum` keyword → `entity.name.type.enum` name remap). An enum gets its
   own `#enum-body` region — keyed on the `*.enum` scope subtype, not the word "enum" —
   whose member matcher captures an identifier in member position (after `{`/`,`, before
   `=`/`,`/`}`), excluding initializer-value identifiers. Object literals and class
   bodies are untouched (the region is enum-only).

Exact-scope drop-in fidelity 71.7% → 74.5%, family-only 19.3% → 16.6%. All gates held:
per-bug strict 100% (37/37, beats official 97.3%), family chart 87.8%, test-issues
318/0 (the two `<` cases now assert relational, matching official), JS 92.6%, sanity
15/15, agnostic 5/5, TSX 22/22. The tree-sitter @operator list only reorders (it does
not split relational/comparison) — semantically identical. scope-coverage now dumps the
per-shape family-only + divergent fix targets so the remaining gaps are explicit.
