refactor(skills): convert absolute paths to workspace-relative + relocate agent-sessions.yaml to .hermes/

Changes:
- skills/lib.sh: AGENT_SESSIONS_YAML default moved from ~/PuKi/lab/.../agent-sessions.yaml
  to <workspace_root>/.hermes/agent-sessions.yaml (relative via BASH_SOURCE)
- 6 SKILL.md: descriptions + 'Single source of truth' lines updated to .hermes/agent-sessions.yaml
- 6 SKILL.md: bash examples (~/PuKi/lab/agent_sessions/skills/...) → relative paths
- SKILL.md file:// links converted from absolute to relative (resolves workspace tool warnings)
- tmux-agent-orchestrate-create/SKILL.md: removed outdated wrapper template reference
- lib.sh internal comments: removed /home/godopu16/PuKi/lab example
- All scripts: internal source/path references use relative resolution

Verified on isolated server -L agy-relative-path-test (kill-server after):
- syntax check PASS
- E2E: create_session.sh auto-creates .hermes/agent-sessions.yaml at new location
- status.sh reads new location correctly
- 0 leftover absolute path references
- Global skill non-interference verified
- Main isolated server -L multi-agent-canary untouched
