refactor(config): migrate multi-category files and config.fish to named sites

Adds multi-site `# COMPONENT` headers and converts every guard call site in
conf.d/tricks.fish, conf.d/abbr.fish, functions/smart_exit.fish,
conf.d/yay-wrapper.fish, conf.d/paru-wrapper.fish, conf.d/wakatime.fish,
conf.d/first_run.fish, and config.fish (9 sites across 3 categories) to the
self-identifying `(status current-function|basename) <site>` calling
convention. Regenerates conf.d/__fish_config_op_registry.fish.
