feat(skills): Add summon — push Desktop sessions across accounts

Push Claude Desktop Code-tab sessions across Claude accounts so they
appear in the next account you switch to. Best run before switching:
copy (default) or move (--move) the session metadata into the
destination account, then Logout/Login as the natural switch.

Features:
- Hierarchical Account -> Project -> Session picker with global numbering
- --peek <id> previews transcript before deciding
- --list-accounts inventory of all logged-in accounts
- Recency aliases (--1d/--3d/--7d/--30d/--all) on top of --days N
- 8-hint rotating tip system (4 conditional + 4 always-eligible)
- Kitchen-sink fs.watch nudge (best-effort; Logout/Login canonical)
- Output follows docs/DESIGN.md panel grammar with ASCII fallback

Validated cross-account file moves via Desktop bundle inspection
(no live fs.watch on session dir; sessions loaded at login).
