perf(graph): compile language-frontend queue globs once - #664
Merged
Conversation
Graph-gates spent ~20% of all-domains build recompiling the same enqueue/worker globs per file. Compile each glob once, skip empty language extractors, and collect independent languages in parallel. Matching and emitted edges stay the same.

rust-no-inline-tests rejects #[cfg(test)] helpers in included source. Keep compile_queue_globs coverage by comparing against Glob::new in the sibling test file.

- Line 30: Add a concise comment immediately above the globs fixture in the
relevant language frontend test, documenting that the invalid "[" pattern is
intentionally included and must remain ignored. Preserve the existing glob
values and test behavior.

Documented the invalid '[' glob fixture. Left Sourcery matcher-lifetime and call-site sharing suggestions as follow-ups; compile-once per emitter is the intended win.

* perf(lang): sequentialize collect_all_lang_facts Nested rayon::join overlapped five language extractors that already file-parallelize, raising language_frontends::extract peak memory 260.8 KB → 688.5 KB. Collect languages one at a time so peak memory returns toward the pre-#664 extract baseline. Facts stay identical. * test(lang): cover partial collect_all_lang_facts configs
