Matrix intake: strip surrounding punctuation from extracted emails

normalize()'s email regex matched non-@/non-space runs, so "Name <addr>"
(the most common contact format) yielded "<addr"; only trailing punctuation
was stripped, never leading. Tighten the regex to standard local@domain.tld
so the bare address is extracted from <…>, (…), and trailing-period forms.
Found via the live-deploy pre-flight. Add a regression test.

Also log two intake backlog items in ROADMAP: the scoped service-credential
auth path (deferred; bot uses a member login for now) and fuzzy match +
in-thread confirm (post-deploy).
