feat: add team session sharing via git repo + SessionEnd hook

[durandom]

Summary

• SessionEnd hook auto-exports Claude Code transcripts to a shared git repo (local commit only, push on demand)
• /fullsend sessions skill subcommand for status, push, pull, and viewing shared sessions in AgentsView
• make sessions target to browse shared sessions in the AgentsView container

How it works

Claude Code session ends
  → SessionEnd hook (.claude/settings.json)
  → export-session.sh (reads stdin JSON)
  → copies transcript + metadata header to <sessions-repo>/<user>_<project>/<session-id>.jsonl
  → git add + git commit (local only)

Configuration via ~/.config/fullsend/sessions.env:

FULLSEND_SESSIONS_REPO=/path/to/team-sessions-repo

The hook exits silently if sessions aren't configured — safe for all team members.

Files changed

File	What
agentsview/scripts/export-session.sh	New — session export script
.claude/settings.json	New — project-level SessionEnd hook
.claude/skills/fullsend/references/sessions.md	New — /fullsend sessions skill reference
.claude/skills/fullsend/SKILL.md	Added sessions to command + routing tables
agentsview/Makefile	Added sessions target

Test plan

• Set up ~/.config/fullsend/sessions.env pointing to a test git repo
• End a Claude session in this project, verify transcript appears in the sessions repo with a local commit
• Run /fullsend sessions — verify status output shows config and session count
• Run make sessions in agentsview/ — verify AgentsView starts with shared sessions
• Verify silent exit when sessions.env is not configured (remove/rename the file)
• Verify idempotency — re-export same session, confirm no duplicate
