Add comprehensive helix-like modal key bindings system for fish shell with: - New `fish_helix_key_bindings` function with helix-inspired navigation - Modal editing support with count modifiers via `fish_bind_count` - Visual mode prompt indicator via `fish_default_mode_prompt` - Enhanced clipboard integration with proper notification formatting The implementation provides vim/helix-style modal editing while maintaining fish shell compatibility and includes proper mode indicators, count tracking, and seamless integration with existing fish key binding systems.

# When defining your own bindings using fish_helix_command, be aware that it can break
|
|
# stuff sometimes.

|
|
# It is safe to define a binding consisting of a lone call to fish_helix_command.
|
|
# Calls to other functions and executables are allowed along with it, granted they don't mess
|
|
# with fish's commandline buffer.
|
|
#
|
|
# Mixing multiple fish_helix_commandline and commandline calls in one binding MAY trigger issues.
|
|
# Nothing serious, but don't be surprised. Just test it.
