"""Centralised path resolution for WritHer.

Provides a single DATA_DIR for all writable files (database, logs, recovery).
- When running from source: uses the project directory
- When running as PyInstaller exe: uses %APPDATA%/WritHer/

Also provides BUNDLE_DIR for read-only bundled assets (icons, images).
