fix(cli): non-blocking startup update check and banner deduplication
- Add background thread mechanism (prefetch_update_check/get_update_result) so git fetch runs in parallel with skill sync and agent init - Fix repo path fallback in check_for_updates() for dev installs - Remove duplicate build_welcome_banner (~180 lines) and _format_context_length from cli.py — the banner.py version is now the single source of truth - Port skin banner_hero/banner_logo support and terminal width check from cli.py's version into banner.py - Add update status output to hermes version command - Add unit tests for update check, prefetch, and version string
