fix: restore Co-authored-by trailer for triggering user (#1271)
The gh-cli migration removed agent/middleware/open_pr.py and
agent/tools/commit_and_open_pr.py — the only callers of
add_user_coauthor_trailer / add_pr_collaboration_note. Since then the
agent has been driving commits and PRs entirely via gh, with no
attribution back to the Slack/Linear/GitHub user who triggered the run.

Resolve the triggering user's identity in get_agent (reusing the
existing authorship helpers) and inject a Collaborative Attribution
section into the system prompt with the exact trailer and PR-body note
to use. The section is only rendered when an identity is resolvable, so
runs without a known triggering user are unchanged.
