teknium1 95b7ea5e5d feat(cli): /init — generate or update AGENTS.md from a project scan
Cross-surface slash command (CLI, gateway, TUI) following the /learn prompt-injection pattern. Port of Codex /init.

"""Tests for /init — generate or update AGENTS.md from a project scan.
Covers the shared prompt builder (hermes_cli.init_command.build_init_prompt)
and the slash-command registry wiring. /init has no engine and no model tool:
it builds a guidance-laden prompt that the live agent runs as a normal turn
(the /learn pattern), so these are the load-bearing behavior contracts.
