Replaces the two hard-coded .qss files with a single
resources/style_template.qss that uses @{token} placeholders.
apply_qss() now does regex substitution at runtime, so adding a
theme only requires a palette dict — no duplicate stylesheets.
New themes (Preferences → Color theme):
• One Dark Pro — VS Code classic dark
• Nord — arctic blue-gray dark
• Tokyo Night — deep purple-dark
• Dracula — classic purple-dark
• GitHub Light — clean minimal light
Existing Catppuccin Frappé (dark) and Latte (light) are unchanged.
Ctrl+Shift+T quick-toggle now recognises all dark themes via is_dark().

execute_script() semicolon splitter (all drivers)
- Add BaseDriver._split_statements() that tracks single/double-quoted
strings and -- / /* */ comments so semicolons inside procedure bodies
are not treated as statement boundaries.
- Replace the naive sql.split(';') in all four drivers with this helper.
- MSSQL execute_script() also pre-splits on GO (case-insensitive, own
line) so scripts pasted from SSMS work correctly.
MSSQL EXPLAIN
- SET SHOWPLAN_TEXT ON/execute/SET SHOWPLAN_TEXT OFF must be separate
execute() calls; pyodbc rejects multiple statements in one call.
Hold self._lock for the entire sequence to keep session state atomic.
Keyring (connections.py)
- Log warnings (with traceback) on load/save failures instead of
silently returning "".
- save_password() now calls delete_password() when password is empty,
so clearing a saved password actually removes the old keyring entry
rather than leaving a stale one behind.
SQLite get_tables() O(N) lock acquisitions
- Run all COUNT(*) queries inside the same `with self._cur() as c:`
block, reducing N+1 lock acquisitions to 1.
Unused import: remove psycopg2.extras from postgres_driver.py.
