Separate the two feed identities so the public read URL never reveals the
inbound address and vice-versa:
- FeedId becomes an opaque high-entropy token (read id + KV key); MailboxId
(noun.noun.NN) owns the inbound address and the untrusted-input boundary
via MailboxId.parse. They map only through the inbound:<mailbox> secondary
index, resolved solely at reception.
- inbound index lifecycle is owned by FeedRepository: written by save/saveConfig,
dropped by removeFromList(Bulk) — symmetric, never mirrored by hand (removes the
manual delete in feed-service + the cron loop, and a silent empty-catch).
- Feed.mailboxId exposes a MailboxId VO (symmetry with Feed.id); the
mailbox@domain shape lives on MailboxId.emailAddress(domain).
- Distinguish mailbox_unknown (no feed claims the address) from feed_not_found
(dangling index) for observability; both forwardable, both 404.
- Drop the redundant EmailParser.extractMailbox pass-through so MailboxId.parse
is the single parse boundary.

Encapsulate the email/domain/feed-id parsing that was scattered as ad-hoc
regexes and split("@") calls into three small immutable value objects under
src/domain/value-objects/. EmailParser.extractFeedId and generateFeedId now
delegate to FeedId; the sender policy, favicon domain extraction and the admin
SenderField parse through EmailAddress/Domain.
Left as-is on purpose: forwardemail's multi-address free-text extraction and the
admin allow/block list normaliser, which operate on mixed email-or-domain input
that the single-address value objects would reject.
Behaviour-preserving; adds unit tests for each value object.
