feat: add local session daemon MVP

[CompoundingWealth]

Summary

• add a profile-local Hermes daemon with Unix socket JSON-lines protocol
• support ping, session.list, session.create, session.get, and shutdown methods backed by SessionDB
• add CLI commands for daemon serve/start/stop/restart/status/sessions/create-session
• document the daemon MVP architecture

Tests

• pytest tests/hermes_cli/test_daemon.py -q -o 'addopts='\n- py_compile hermes_cli/daemon.py hermes_cli/main.py tests/hermes_cli/test_daemon.py\n\n## Notes\n- This is the conservative foundation for jcode-style daemon-owned sessions and thin clients. It does not yet run daemon-owned agent workers or stream events.

[CompoundingWealth]

Added second commit 6b00adcd7 on the PR branch.

New slice:

• session.send starts daemon-owned background agent runs
• run.get returns run status/result/error
• session.events returns bounded in-memory event stream
• CLI: hermes daemon send ... and hermes daemon events ...
• tests expanded from 3 to 5 daemon tests

Verification:

• TMPDIR=/tmp ~/.hermes/hermes-agent/venv/bin/python -m pytest tests/hermes_cli/test_daemon.py -q -o 'addopts=' → 5 passed\n- ~/.hermes/hermes-agent/venv/bin/python -m py_compile hermes_cli/daemon.py hermes_cli/main.py tests/hermes_cli/test_daemon.py → passed
