Subject: [PATCH] feat(hook): add spawn_id correlation to amc-hook

Read AMC_SPAWN_ID env var and include spawn_id in session JSON when
present. This enables deterministic spawn correlation: the server
generates a UUID, passes it via env to the spawned agent, and then
polls for a session file containing that specific spawn_id.

Closes: bd-1zy
