Populate traits and email in agent passport templates

`drone @spawn create --traits "..."` accepted the flag and silently
discarded it: the TRAITS placeholder is built in placeholders.py but no
template referenced it. Same for EMAIL — the registry recorded @<agent>
while the passport had no email key, so the identity hook rendered
"Email: unknown" for every agent.

Both placeholders were already wired; only the templates needed to use
them. Applied to aipass_framework and project_agent alike.

The identity hook reads traits as either list or string and skips the
line when falsy, so an agent created without --traits is unchanged.

Also regenerates aipass_framework's .template_registry.json, which drops
seven stale .pytest_cache entries for files not present in the template.
