* test(go): add #1848 Go pipeline + worker-pool benchmark

* optimize(go-scope-capture): thread captured nodes to kill O(n^2) findNodeAtRange re-walks
emitGoScopeCaptures re-derived each match's AST node via findNodeAtRange from
the tree root on every query match, giving O(matches x rootChildren) ~ O(n^2)
behaviour (the #1848 root cause: a 250-struct generated DAO took ~10.8s, 800
structs ~100s+ — long enough to trip the worker sub-batch idle timeout and get
quarantined). Thread the query-captured SyntaxNode (c.node) through a parallel
tag->node map and use it directly (or via a bounded local parent walk for the
import_declaration ancestor case) instead of re-walking from root.
Output is byte-identical (capture fingerprint over the DAO file + all 89 go-*
fixtures unchanged; capture_groups=13501). 250 entities: 10835ms -> 114ms (95x).
800 entities: ~100s -> 384ms. Go resolver + scope-resolution suites: 165/165 pass.

* test(go-scope-capture): address code-review findings
Self-review (ce-code-review) polish on the #1848 fix + benchmark:
- benchmark: tighten the scaling guard from timeRatio/fileRatio < 3 to < 1.5.
At the 2.5x/2x scale steps, a quadratic regression yields ratio == fileRatio
(2.5, 2.0), which < 3 waved through — the guard could not detect the O(n^2)
it exists for. Measured O(n) ratios are 0.45/0.59, so < 1.5 has headroom.
- benchmark: add a non-gated O(n^2) regression tripwire that calls
emitGoScopeCaptures on a 400-struct source directly (no worker, no
GITNEXUS_BENCH gate) so the regression is actually guarded in CI.
- benchmark: clearTimeout the Promise.race timer in finally (no lingering
rejection); set the worker-suite env vars inside the try so finally always
restores them.
- captures.ts: clarify the isRawMultiAssignTypeBinding comment to name both
var-form cases (assertion + call-return). Comment-only.
Left as-is: resolveImportNode's defensive range-equality branch — deleting it
as dead code would remove the self-documentation of the grammar invariant the
threaded-node logic depends on (reviewer tension; a wash).
Verified: tsc clean; 165/165 Go resolver + scope tests; new tripwire passes
(237ms); scaling suite passes at <1.5; #1848 worker suite still green.

* test(go): golden capture-parity guard for emitGoScopeCaptures (#1848 U1)
Pins emitGoScopeCaptures output across all 89 go-* fixtures + a synthetic DAO
shape as a committed golden (test/fixtures/go-captures-golden/expected-captures.json),
so future drift in the Go scope-capture path fails CI instead of only the coarse
perf tripwire. Match-grouped, order-independent sha256 canonicalization; regenerate
intentionally with UPDATE_GOLDEN=1. Mirrors test/integration/pipeline-graph-golden.test.ts.

* test(go): cover func_literal, var-form bindings, single import, generics (#1848 U2)
Adds smoke cases for the Go shapes the #1915 captured-node refactor reasons
about but no lang-resolution fixture exercised: func_literal under @scope.function
(no receiver synthesized), var-form @type-binding.assertion and .call-return (not
dropped by isRawMultiAssignTypeBinding), a single unparenthesized import through
resolveImportNode, and a generic function declaration.

* test(go): tighten O(n^2) tripwire budget 10s -> 5s (#1848 U3)
The fixed path is ~250ms; a quadratic regression at 400 structs is ~25s. 5s keeps
~20x headroom over the fixed path while tripping a ~20x regression (vs the prior
~40x). Correctness is guarded separately by the U1 golden test, so this stays a
pure perf tripwire.

* chore(autofix): apply prettier + eslint fixes via /autofix command
* test(go): fail on a missing golden in CI via a pure resolveGoldenAction helper (#1848 U1)
Extracts the golden test's missing-file gate into a pure
resolveGoldenAction({update,exists,isCI}) -> regenerate|compare|fail helper, so
a missing golden no longer self-heals + passes in CI (Codex F2). The rule is
unit-tested directly across all combos with no filesystem mutation (can't corrupt
the committed golden). CI detection uses a truthy check (!!process.env.CI) so it
fires on any runner. Locally a missing golden still regenerates as first-run convenience.

* test(go): make the golden digest order-sensitive (#1848 U2)
Drops the cross-match .sort() in digestCaptures so the digest reflects emission
order — a true byte-identical guard that catches a reordering refactor (Codex F1),
not just a set-equality check. Safe because emitGoScopeCaptures output is
deterministic. Within-match key order stays normalized (a CaptureMatch is a Record).
Replaces the order-independence test with an order-sensitivity assertion and
regenerates expected-captures.json under the new scheme (all 90 digests).
Trade-off: a tree-sitter-go grammar bump that reorders matches now requires a
deliberate UPDATE_GOLDEN=1 regen — intentional (a tree-shape change deserves a look).

* test(go): strengthen func_literal smoke case to a positive receiver assertion (#1848 U3)
The old case used a closure-only source and only asserted ABSENCE of
@type-binding.self, so it would pass even if the method_declaration receiver
branch regressed (Codex F3). The fixture now has both a method and a closure, and
positively asserts exactly one @type-binding.self from the method (name=u,
type=User — the type also confirms *User pointer-stripping) and none from the closure.

* fix(test): remove TOCTOU file-system race in golden test + format
CodeQL flagged a high-severity 'potential file system race condition': the golden
test did fs.existsSync(GOLDEN_FILE) then later writeFileSync/readFileSync on it.
Replace the existsSync-then-use with a single race-free read (ENOENT => missing),
reusing the read content for the compare path. Behaviour is unchanged (the pure
resolveGoldenAction helper still decides regenerate/compare/fail). Also applies
prettier formatting to the file (fixes the quality/format check).

* fix(go): use loose equality for Array.find() null checks (#1346, #1366)
Array.find() returns undefined (not null) when no match is found, but
the code checked with === null / !== null which fails to intercept it.
This caused "Cannot read properties of undefined (reading 'type')" and
"Cannot read properties of undefined (reading 'namedChildren')" crashes
on Go files containing plain for loops, make(chan T), or other patterns
where the expected tree-sitter node type is absent.
* refactor(go): use strict undefined checks for Array.find() results
Address review feedback: Array.find() returns undefined by spec, so
check with === undefined / !== undefined instead of loose == null.
