Merge branch 'dev' into migrate-project

Replace Bun-specific file operations with Filesystem module and fs/promises:

- Add stat import from fs/promises

- Replace Bun.file().text() with Filesystem.readText()

- Replace Bun.file().write() with Filesystem.write()

- Replace Bun.file().arrayBuffer() and .type with Filesystem.readBytes() and mimeType()

- Replace Bun.file().stat() with stat() from fs/promises

All 18 project tests pass.
