Per-function overrides: C0/always

Every guarded function or file can also carry a reserved always/on or always/off tag in its # COMPONENT header, independent of every C1-C6 category and sub-category toggle and invisible to config-settings. An always/off tag disables that function unconditionally; an always/on tag enables it unconditionally, ignoring the state of every other tagged sub-category. This is a per-function escape hatch for cases too granular or too idiosyncratic to justify a taxonomy entry -- edit the header directly and run __fish_config_op_registry_rebuild to apply the change.
