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.
