feat(manifest): lift git.user to the agent layer

Agents may declare git.user (name/email); it overlays the referenced
bottle's git.user per-field at Manifest.bottle_for (agent wins on
non-empty), mirroring the extends: merge. git.remotes is rejected on
agents — it carries credentials and host trust and stays bottle-only.

The overlay lives at bottle_for, the single chokepoint both backends
use, so the docker/smolmachines git provisioners are unchanged. Adds
Manifest.git_identity_summary with per-field (agent)/(bottle)
provenance, printed in both preflights and `info`.
