Add OS file association for database files (.db, .sqlite, .sqlite3, .duckdb)
so double-clicking them in Finder/Explorer automatically creates a connection.
If the same file path is already connected, prompts the user to switch instead.
Also fix 42 pre-existing clippy warnings in dbx-core (needless_borrow,
too_many_arguments, derivable_impls, manual_div_ceil, type_complexity, etc.).
Closes#527

Disable all CSS transitions/animations during theme toggle so color
changes apply instantly instead of animating over 150ms. Also cache
Tauri window module import and set color-scheme for native UI elements.

now reuses the warm daemon instead of spawning a new JVM each time. If the
daemon dies, it auto-respawns on next call.
