[codex] Add mojidata-api bundler-safe entrypoints

[mandel59]

Summary

• Add documented bundler-safe @mandel59/mojidata-api facade entrypoints for browser, worker protocol, SQL.js Node, better-sqlite3, and node:sqlite targets.
• Expose stable runtime and sqlite-wasm public subpaths so mojidata-web-app does not need private lib/* imports.
• Add static entrypoint smoke tests to catch browser/Cloudflare-unsafe imports and validate the sqlite-wasm OPFS public path.
• Validate sqlite-wasm idsfind.db schemas as FTS5 and document the @mandel59/idsdb-fts5 requirement.

Validation

• corepack yarn node --import tsx --test ./tests/*.test.ts in packages/mojidata-api
• corepack yarn node --import tsx --test ./tests/*.test.ts in packages/mojidata-api-sqlite-wasm
• corepack yarn install --immutable

Notes

This branch is based on cloudflare because the local work was built on top of the current D1/API deployment branch.
