fix: restore missing sqlite/observations/files.js shipped module

[E0993599799]

Summary

• worker-service.cjs dynamically requires ../sqlite/observations/files.js via createRequire(__IMPORT_META_URL__), sourced from src/services/sqlite/observations/files.ts. This file is intentionally excluded from the main esbuild/bundler output (it's loaded lazily at runtime instead of being statically bundled), but the build does not currently copy/compile it into the shipped plugin/ output directory.
• As a result, every Chroma backfill and live observation sync fails at formatObservationDocs → jce() with:

  ResolveMessage: Cannot find module '../sqlite/observations/files.js' from '.../plugin/scripts/worker-service.cjs'
  

• This silently breaks Chroma vector sync for all users on affected installs — primary SQLite storage and FTS5 full-text search keep working, but semantic/vector search over memories never gets populated.

Fix

Adds the missing module at the exact path worker-service.cjs resolves it to:

• plugin/sqlite/observations/files.js — minimal, dependency-free CommonJS reimplementation of parseFileList (the only export this call site needs). Left dependency-free (no utils/logger.js import) since that module isn't shipped in plugin/ either.
• plugin/sqlite/package.json — { "type": "commonjs" }, so Node/Bun parse the .js file as CommonJS despite the parent plugin/package.json declaring "type": "module" (Node resolves module type from the nearest package.json up the directory tree).

This is a packaging-only fix at the shipped-output level. The real fix likely belongs in the build pipeline (src/build) so this file gets compiled/copied automatically on release — flagging that as the more durable long-term fix, but wanted to get a working patch out first.

Test plan

• Reproduced: confirmed the exact Cannot find module '../sqlite/observations/files.js' error in a live worker's logs, across every project during backfill.
• Simulated the exact createRequire(pathToFileURL(worker-service.cjs).href)("../sqlite/observations/files.js") call directly with bun — resolves and returns parseFileList correctly after the fix.
• Restarted the worker for real with the fix applied: Chroma backfill succeeded end-to-end for multiple projects (Dheva-oracle-deploy, aeimathes-oracle, aris-oracle, captain-maid/*, ...) with zero module-resolution errors, where previously every single project failed at this step.

Greptile Summary

This PR restores a missing shipped helper used by Chroma observation sync. The main changes are:

• Adds plugin/sqlite/observations/files.js with a dependency-free CommonJS parseFileList export.
• Adds plugin/sqlite/package.json to make files under plugin/sqlite/ load as CommonJS despite the parent ESM package.
• Restores the runtime path resolved by worker-service.cjs for observation document formatting.

Confidence Score: 5/5

Safe to merge with minimal risk.

The change is narrowly scoped to adding a missing packaged runtime module and local module-type boundary. The helper mirrors the existing source behavior needed by Chroma observation formatting. No new external dependencies or security-sensitive data flow were introduced.

No files require special attention.

T-Rex Logs

What T-Rex did

• The initial smoke-check run showed a module-resolution failure for the sqlite/observations/files.js path when it was missing, exiting with code 1.
• After shipping the updated plugin, the smoke-check succeeded and reported the expected module-resolution outputs, including exportedKeys parseFileList and parseFileListType, with exit code 0.
• The parse-file-list tests under tests/services/sqlite passed in Bun, totaling 9 passing and 0 failing, with exit code 0.
• A smoke-check script named plugin_sqlite_resolution_smoke.cjs was generated to encapsulate the module-resolution check and enable reproducible validation.

Important Files Changed

Filename	Overview
plugin/sqlite/observations/files.js	Adds the shipped CommonJS parseFileList helper at the runtime path resolved by worker-service.cjs; behavior matches the source helper except for omitted debug logging.
plugin/sqlite/package.json	Adds a scoped type: commonjs package boundary so the shipped helper is loaded as CommonJS under the ESM plugin package.
