aneurinandClaude Sonnet 5 a992065d6c email: validate with net/mail.ParseAddress

Replace the RFC 5322 mega-regexp with net/mail.ParseAddress, which is the
standard library's address parser and far easier to audit. A bare address
is required: inputs with a display name, angle brackets, a comment, or
trailing content are rejected, as is an address list.

Behaviour change: ParseAddress does not require the domain to contain a
dot, so "alice@localhost" now validates. Layer Match or a DNS lookup on
top if a stricter domain is needed.

Also rewrites FuzzEmail, which previously asserted that *every* input is
invalid, into checks that Email never returns an unexpected error type,
never panics, and gives a stable verdict.
