feat(config-help): add --html and --man flags; add config-update function

config-help gains two new flags:
- --html / -w: opens docs/html/index.html in the default browser using
  smart browser detection (xdg-mime https scheme handler → known binaries
  → xdg-open fallback) to avoid MIME-type mismatches with non-browser apps
- --man / -m: opens the compiled docs/fish-config.1 man page via man -l

config-update is a new function that pulls the latest fish config from the
hard-coded upstream URL without requiring a configured git remote. Suppresses
git output and reports status with colored messages. Supports --dry-run and
--force flags.

README updated to document all new commands.
