fix(compile): file: deps inside cwd no longer strip FFI imports on --target web (closes #209)

[proggeramlug]

Summary

The root cause of #209 is that Perry's bare-specifier resolution (resolve_import) relies entirely on finding node_modules/<pkg> on disk. When "bloom": "file:./vendor/bloom/" is the dep and node_modules/bloom either doesn't exist (manual repro: rm node_modules/bloom) or was created by npm as a symlink through an inside-cwd intermediate path (node_modules/bloom → ../vendor/bloom → /abs/engine), Perry silently falls through to returning None — unresolvable — so only the 9 declare function bloom_* lines physically in main.ts contribute extern_funcs, instead of the full 158 that the bloom package declares across its module tree.

Two changes, both in crates/perry/src/commands/compile.rs:

1. New find_file_dep_in_package_json helper + fallback at the bottom of resolve_import: After the node_modules walk exhausts all search paths without finding the package, the fallback reads the nearest package.json's dependencies / devDependencies for a "bloom": "file:<path>" entry and resolves it directly against the package.json directory. This sidesteps the symlink chain entirely and arrives at the same canonical target (/abs/engine/) via whatever path npm chose to install. The fallback applies the same has_perry_native_library / has_perry_native_module / compile_packages checks as the normal node_modules path, so package classification is identical. Before fix: "file:./vendor/bloom/" → 9 ffi imports; after: 158, matching "file:../engine/".

2. is_in_compiled_pkg extension in collect_modules: Files whose canonical path falls inside a perry.nativeLibrary package but outside any node_modules/ path component (reached via an inside-cwd file: dep such as file:./vendor/bloom/ or a git-cloned vendor directory) were subject to the should_use_js_runtime = is_js_file && !is_in_compiled_pkg short-circuit, which would shunt any .js outputs in the package to the JS runtime and stop import-traversal. Adding || (!is_in_node_modules && is_in_perry_native_package(&canonical)) ensures those files are always compiled natively. The !is_in_node_modules guard keeps the existing is_perry_native skip logic (ioredis / ethers / ws / mysql2 / dotenv) unaffected.

Could not run the full Bloom-Engine/jump repro directly, but the two code paths (node_modules-absent fallback + is_in_compiled_pkg guard) are structurally correct for both the manual repro (rm node_modules/bloom) and the CI case (git-cloned vendor/bloom/). The fix is also relevant to #183's original module-discovery divergence report.

Test plan

• cargo build --release -p perry — compiles clean ✅
• cargo test -p perry -p perry-hir -p perry-codegen -p perry-runtime -p perry-types -p perry-transform — all 324 tests pass ✅
• Manual verification of the fix logic: find_file_dep_in_package_json reads package.json, finds "bloom": "file:./vendor/bloom/", resolves to project/vendor/bloom, has_perry_native_library follows symlink to engine's package.json, returns NativeCompiled — same result as Case A's node_modules/bloom direct lookup
