fix CLI exit and agents storage docs (#113, #114)

diff --git a/src/agents.rs b/src/agents.rsindex 11a1a72..aecb428 100644--- a/src/agents.rs+++ b/src/agents.rs@@ -61,7 +61,7 @@ fn agents_markdown(6161          On success the server shows a `received` page with a one-time ack uuid (shown once, not in a URL, no lookup endpoint) and reflects nothing back (kills reflected XSS). No GET, no listing, no read-back. Inbox never appears in the site; accepted text shows up later as a real issue/PR.\n\n\6262          ### License (required — check the box only if you agree)\n\n\6363          > {license}\n\n\64-         Stored per submission: license version + checkbox state + body hash + timestamp. No submission without the box checked.\n\n\64+         Stored per submission: type, title, body, optional handle/contact, license version, `received_at`, and a salted source-IP hash. The checkbox is validated before storing; no submission is accepted without it.\n\n\6565          ## Philosophy\n\n\6666          - Issues = detailed actionable text from your user. Write what a maintainer can act on: context, steps, expected vs actual, links to `/raw/` paths.\n\6767          - PRs = ONE prompt not code. Send a single plain-text prompt describing the change; never send files, diffs, branches, or bundles. Code words inside stay text — never applied, never executed.\n\
