Match complete AI identity tokens in email addresses.

Co-authored-by: Aidan Smith &lt;agent.aidan@example.com&gt; matches agent.ai inside the localpart and fails the check. Require a token boundary after agent.ai or assistant.ai so that human addresses remain valid.

Review comment at @scripts/commit-check.sh at line 51:
Update the AI-identity email pattern in the `_co` check so `agent.ai` and `assistant.ai` match only as complete local-part tokens, requiring a token boundary immediately after the identity token. Keep the existing separators and `@` handling, and allow human addresses such as `agent.aidan@example.com`.

Continue detecting built-with attribution in HTML comments.

&lt;!-- built with Claude --&gt; previously matched the vendor rule, but it does not match the new vocabulary or any other shown rule. The check therefore accepts this AI attribution. Include built in the attribution vocabulary, or match the complete built-with-vendor form.

Review comment at @scripts/commit-check.sh at line 93:
Update the attribution pattern in the `_msg` check to recognize “built” in HTML comments, so built-with vendor attributions are rejected while existing attribution detection remains unchanged.

Do not reject ordinary comments containing attribution verbs.

&lt;!-- changes made for compatibility --&gt; now fails the commit check even though it contains no attribution. Match attribution context rather than a verb alone, so ordinary comments can pass.

Review comment at @scripts/commit-check.sh at line 93:
Update the attribution check on _msg so it detects attribution context rather than rejecting comments merely because they contain a verb such as “made.” Preserve detection of actual attribution while allowing ordinary comments like “changes made for compatibility” to pass.
