Implement a word-level scoring engine for the command palette that replaces
the previous FZF-based approach. Query tokens are matched against pre-tokenized
words in each column (key, action, category) with exact, prefix, and
edit-distance scoring. Multiple search terms are supported with cross-column
matching — items matching more tokens rank higher. Compound query tokens
containing delimiters (e.g. mouse_selection) are matched as units.
Add comprehensive tests using a Go builder API instead of raw JSON blobs,
covering single-token, multi-token, partial-match, ranking, mouse binding,
and unmapped action scenarios.
Add documentation for the command palette kitten.
When a USB HID device (keyboard/mouse) is disconnected, X11 fires an
XI_HierarchyChanged event, which triggers read_xi_scroll_devices().
That function calls XIGetProperty() on devices from XIQueryDevice().
There is a race condition: if a device is removed between these calls,
X11 generates an XI_BadDevice error. Without a custom error handler, the
default X11 handler calls exit(), killing kitty.
Fix: wrap the device query loop in read_xi_scroll_devices() with
_glfwGrabErrorHandlerX11() / _glfwReleaseErrorHandlerX11() so that any
XI_BadDevice error is captured by kitty's own handler rather than the
default fatal one.

The regression was introduced by commit b277a016b which added an early
`return` in handle_button_event that prevented kitty's internal text
selection from starting on focus-transfer clicks to unfocused splits.
Changes:
- In handle_button_event: replace the early return with a local
suppress_child_forwarding flag that prevents PRESS from being forwarded
to child processes in mouse-tracking mode, while still allowing
dispatch_mouse_event to run (which starts text selection)
- In mouse_event's active_drag_in_window release path: clear
suppress_left_mouse_release to prevent stale flags after drags

This ensures that Ctrl+H behaves like Backspace and correctly clears
the pre-edit state, preventing uncommitted characters from remaining
on the screen when using IMEs like the Japanese one on macOS.
