Jason Rayne 81641e56b1 ssh-integration: replace levels with flags, optimize implementation ...

Rewrote shell functions to support the two new flags for
shell-integration-features:
- ssh-env: TERM compatibility + best effort environment variable
propagation (anything beyond TERM will depend on what the remote host
allows)
- ssh-terminfo: automatic terminfo installation with control socket
orchestration
- Flags work independently or combined

Implementation optimizations:
- ~65% code reduction through unified execution path
- Eliminated GHOSTTY_SSH_INTEGRATION environment variable system
- Replaced complex function dispatch with direct flag detection
- Consolidated 4 cache helper functions into single _ghst_cache()
utility
- Simplified control socket management (removed multi-step
orchestration)
- Subsequent connections to cached hosts are now directly executed and
more reliable

New additions:
- If ssh-terminfo is enabled, ghostty will be wrapped to provide users
with convenient commands to invoke either of the two utility functions:
`ghostty ssh-cache-list` and `ghostty ssh-cache-clear`
