Per-file LSP (run from cbm_extract_file) only sees one file's defs, so
callees whose receiver type comes from an imported module stayed
unresolved — even though Go/C/Py/TS already had cross-file entry points
(cbm_run_X_lsp_cross). Those entry points existed but no pipeline pass
ever invoked them. PHP didn't even have a cross-file entry point.
This change lands the missing pieces:
1. cbm_run_php_lsp_cross + cbm_batch_php_lsp_cross — PHP cross-file
resolver mirroring py_lsp_cross / ts_lsp_cross. Reuses PHPLSPContext,
php_lsp_init, php_lsp_add_use, php_lsp_process_file. Handles PHP-
specific labels (Class / Interface / Trait / Enum / Type) and uses
def_module_qn so cross-file return types qualify against the def's
own module rather than the importing module's.
2. pass_lsp_cross.c — new pipeline pass. For every cached file result,
builds a project-wide CBMLSPDef[] (CBMDefinition → CBMLSPDef
converter), per-file import map (from gbuf IMPORTS edges), then
dispatches to the matching cbm_run_X_lsp_cross. Output strings get
copied into the per-file arena (with O(N²) memory bug avoided by
running each file inside a fresh scratch arena that gets destroyed
after the LSP call — the LSP allocates its registry + stdlib +
project defs in scratch, not in the caller's persistent arena).
3. Wired into both pipelines:
- sequential: definitions → k8s → lsp_cross → calls → ...
- parallel: parallel_extract → registry_build → lsp_cross →
parallel_resolve → ...
4. Updated tests/test_parallel.c run_parallel helper to mirror the new
parallel ordering so existing cross-file Python/PHP tests now exercise
pass_lsp_cross.
Languages covered: Go, C/C++/CUDA, Python, TS/JS/JSX/TSX, PHP. PHP cross
file is new. The other four had functions but no pipeline integration
until this change.
Verified on a 1670-file FastAPI index: pass_lsp_cross processes 1050
Python files (525 non-LSP files skipped), collects 4070 project defs in
9.2s, and parallel_resolve subsequently reports lsp_overrides=568 — the
LSP-strategy attribution gain over per-file alone.
Per-LSP emit functions dedup by (caller_qn, callee_qn) within their own
run; pxc_append_results dedups again at append time so cross-file
entries duplicating per-file output get dropped instead of inflating
result->resolved_calls.
