Lawrence Chen 777d6b048e Replace CLAUDE_CONFIG_DIR with claude wrapper + richer notifications
Instead of creating a merged config directory and injecting
CLAUDE_CONFIG_DIR on every terminal spawn, place a thin wrapper
script at Resources/bin/claude that intercepts claude invocations
to inject --session-id and --settings flags. This eliminates
blocking I/O on terminal creation and removes config management
complexity.

- Add Resources/bin/claude wrapper script with hook injection
- Add shell integration PATH fix (re-prepend after .zshrc/.bashrc)
- Add transcript reading for richer stop notifications
- Add set_status/clear_status to notifications socket allowlist
- Add Settings toggle to disable Claude Code integration
- Update docs to reflect automatic integration approach
- Unset CLAUDECODE env var to avoid nested session detection

# cmux claude wrapper - injects hooks and session tracking
#
# When running inside a cmux terminal (CMUX_SURFACE_ID is set), this wrapper
# intercepts `claude` invocations to inject --session-id and --settings flags
# so that Claude Code hooks fire back into cmux for notifications/status.
# Outside cmux, it passes through to the real claude binary unchanged.
# Find the real claude binary, skipping our own directory.
