TASK-120	Replace node:sqlite with libsql and remove Yomitan Node wrapper	Done		2026-03-08 04:14	2026-03-16 05:13	runtime bun sqlite tech-debt		medium	65500

Description

Remove the remaining root Node requirement caused by immersion tracking SQLite usage and the old Yomitan build wrapper by migrating the local SQLite layer off node:sqlite, running the SQLite-backed verification lanes under Bun, and switching the vendored Yomitan build flow to Bun-native scripts.

Acceptance Criteria

• #1 Immersion tracker runtime no longer imports or requires node:sqlite
• #2 SQLite-backed immersion tracker tests run under Bun without Node --experimental-sqlite
• #3 Root build/test scripts no longer require the Yomitan Node wrapper or Node-based SQLite verification lanes
• #4 README requirements/testing docs reflect the Bun-native workflow

Final Summary

Replaced the immersion tracker SQLite dependency with a local libsql-backed wrapper, updated Bun/runtime compatibility tests to avoid process.exitCode side effects, switched Yomitan builds to run directly inside the vendored Bun-native project, deleted scripts/build-yomitan.mjs, and verified typecheck plus Bun build/test lanes (build:yomitan, test:immersion:sqlite, test:runtime:compat, test:fast).
