Two of the three fixes from PR #6660 (the cli.py reopen_session change is
moot — that raw _conn.execute reopen block no longer exists on main).
- gateway/run.py: stop sending raw type(e).__name__ and str(e)[:300] to
end users on chat platforms. Exception text from LLM providers can leak
API URLs, file paths, and partial credentials. Return a generic message;
keep curated status hints for known HTTP codes; full detail stays in logs.
- gateway/platforms/webhook.py: validate pr_number (positive int) and repo
(owner/name regex) before passing to the 'gh pr comment' subprocess.
Payload-controlled values could otherwise inject gh flags (--help, a
different --repo). List-form subprocess means this is arg injection, not
shell injection, but validation is still correct.
