fix(java): materialize record component accessors (#2936)
* fix(java): materialize record component accessors

* fix(java): ignore receiver params in record accessor arity

* fix(java): address record-accessor review findings (#2917)

Five findings from the tri-review of #2936.

P1 — a synthesized callable evicted a source-written one from the method map.
`getMethodInfo` keyed its per-class map by `name:line`, but a callable that is
SYNTHESIZED at a position that is not its own declaration shares its owner's
line: a record's implicit accessor is minted at the component, and a C# 12
primary constructor at the owner's `parameter_list`. Both are appended last by
their extractor, so on a single line the synthesized entry overwrote the
explicit method's MethodInfo and both definitions collapsed onto one id —
`record P(int x, int y) { int x(int s) {...} }` lost `P.x#1` and rebound the
arity-1 call to the zero-argument accessor. Adds a required `MethodInfo.column`
and keys the map by `name:line:column` through a single `methodInfoKey` helper.
Required, not optional: an absent column would key an entry no lookup could
reach — a silent, whole-language loss of enrichment instead of a compile error.
All three lookup sites move together; the file's own lockstep docblock warns
that a half-applied change loses caller edges silently rather than dangling.
This also fixes the same collision in C#, which never touched record code.

Degenerate component names no longer mint a node. tree-sitter's zero-width
MISSING recovery token satisfies `name: (identifier)`, so `record M(int x, y) {}`
minted an empty-named Method whose returnType was the neighbouring `y`; and the
grammar admits `underscore_pattern` in the same field, which the query rejected
but the scope path accepted, so `record R(int _) {}` left a scope declaration
with no node behind it. One `isRecordComponentName` predicate now gates all
three emitters — query suppression, scope synthesis, and the method extractor —
so they cannot drift apart again.

Component annotations reach the implicit accessor (JLS 8.10.3 / 9.7.4) by
reusing the shared `extractAnnotations` helper. Deliberately over-approximate
and commented as such: `@Target` lives in another file and parsing is per-file.

`explicitZeroArgAccessorNames` is memoised per record node. It was rebuilt on
every component capture — O(components x body members) for one record, measured
at ~4x per 2x input — while the scope path already hoisted the identical call.

Docs: the `java-local-types` baseline now stores the `capture_groups_fp` its own
note cites, the SCHEMA_BUMP ledger no longer claims a v65 that nothing holds,
and `shouldSkipDefinitionCapture` documents that `defaultLabel` may be ignored.

Scope-capture fingerprints are unchanged (`measure.mjs --check` PASS, 15
languages): the bench corpus contains no degenerate components, so the new
predicate is inert on it. SCHEMA_BUMP stays 67 — this branch's existing claim
already covers the changed worker output; re-check it against origin/main before
merging.

* docs(ingestion): reunite the overload-suffix JSDoc with typeTagForId

The block describing the `~type1,type2` same-arity discriminator was stranded
above `buildCollisionGroups` when that function was inserted between it and the
`typeTagForId` it documents (#658). Adding `methodInfoKey` in this branch parked
it directly above yet another unrelated function, which gitnexus-check flagged.

Moves the comment down to the function it describes. No behaviour change.
