The previous implementation reverted any keyboard-driven window switch
on the next mouse motion event because it compared the hovered window
against the active window rather than against the previously hovered
window. Move the focus-follows-mouse trigger into
set_currently_hovered_window so it fires only when the hover ID
actually transitions, which also covers OS-window-entry.
Replace the brief Searching section with a structured user-facing
explanation covering: multi-word queries, per-word matching (exact,
prefix, and typo tolerance), compound names with delimiter characters,
and the five-level ranking order.
diff.g was used twice instead of diff.g + diff.b, causing the
same-color detection to miss blue-only differences. This meant
the HSLuv contrast override could skip adjustment for color pairs
differing primarily in blue.

Users who define action_alias or kitten_alias in kitty.conf had no way
to discover or trigger these custom commands from the command palette.
Aliased keybindings were miscategorized (landing in "Miscellaneous"
with no help text), and combine bindings had the same problem.
Changes:
- Resolve aliases via opts.alias_map to get correct action names,
categories, and help text for aliased keybindings
- Add dedicated "Action aliases" and "Kitten aliases" sections that
list all user-defined aliases, with bound aliases showing their key
and unbound aliases browsable as unmapped entries
- Add a "Combined actions" section for combine keybindings
- Make alias names searchable in the Go TUI so users can find
bindings by typing the alias name
- Fix action column highlight positions to match the scored text,
preventing visual corruption when searching for alias names
Also refactors collect_keys_data into focused single-responsibility
functions and reduces nesting depth across both Python and Go.
Refactored so text_width_for_single_line is called inside draw_window_title
after CSI stripping, avoiding stripping the same text twice. The standalone
text_width_for_single_line wrapper is removed; draw_window_title now accepts
a size_t *actual_width output parameter that, when non-NULL, triggers text
width calculation and width reduction.

Timing-safe comparisons:
- crypto.c: Replace memcmp with CRYPTO_memcmp for Secret equality,
require equal lengths before comparing
- remote_control.py: Constant-time password lookup to avoid leaking
valid passwords via dict hash timing
- file_transmission.py: Use hmac.compare_digest for bypass token
comparison instead of ==
Memory safety:
- child-monitor.c: Fix inverted condition in write_to_peer that
prevented memmove from ever executing on partial writes
- ibus_glfw.c: Null-terminate IBUS_ADDRESS copy to prevent string
overread when strlen >= PATH_MAX
- x11_window.c: Add NULL checks after realloc in clipboard/DnD
data handling (two sites)
- dnd.c: Cap accepted_mimes at 1MB to prevent unbounded growth,
fix realloc to not lose the original pointer on failure
- png-reader.c: Cast to size_t before multiplication to prevent
integer overflow on 32-bit platforms
Secrets hygiene:
- disk-cache.c: Zero encryption_key with explicit_bzero before free
Tar extraction hardening:
- tar.go: Validate hardlink targets against destination prefix to
prevent writing outside extraction directory
- tar.go: Strip setuid/setgid/sticky bits from extracted files
