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.
When kitty loses focus and the user scrolls in another
application, X11 XI scroll valuators accumulate position values. When the
user returns to kitty and scrolls, delta (value - v->value) uses the stale
pre-focus-loss value, causing a massive unexpected scroll jump.
Fix: reset scroll valuators (mark them uninitialized) on FocusOut so the
first scroll event after focus is regained sets the baseline without firing
a scroll event.
