The TLS connection state lived on the shared POP3 Server, and Session
reached it through its embedded *Server. Once any client completed
STLS, every later session saw a non-nil state: CAPA stopped advertising
STLS and the STLS command returned "-ERR A TLS session already agreed
upon." until the server restarted. Sessions also wrote the shared field
concurrently without synchronization.
Move tlsState to Session. ForceTLS sessions set it when the session
starts, and STLS sets it on the negotiating session only.
TestSTLSPerSession runs CAPA, STLS and a TLS handshake on two sessions of
one server; it fails against the previous code on the second session.

- RETR and TOP now respond "-ERR You deleted message N" for messages
marked deleted, as RFC 1939 sections 5 (RETR) and 7 (TOP) require;
previously the message content was still sent.
- STLS: a failed TLS handshake previously continued the session with
the dead TLS connection installed as s.conn and a bogus tlsState,
producing confusing follow-on errors. RFC 2595 section 4 requires
the negotiation to complete before further commands, so a failure
is now fatal: log it and terminate the session.
Updates the scripted tests that previously pinned the old behavior,
and adds a STLS handshake failure regression test.

- validateMsgNum parses and range-checks message-number arguments,
replacing five copies of the parse/check/respond sequence in the
LIST, UIDL, DELE, RETR and TOP arms (wire responses unchanged).
- listMessages implements LIST and UIDL, which differ only in the
per-message value reported.
- sendMessageLines unifies sendMessage/sendMessageTop via a body line
limit, negative meaning unlimited.
Adds a direct unit test for validateMsgNum and an equivalence test
asserting TOP with a large line limit matches RETR output. All
scripted session tests from the previous commit pass unchanged.

Covers the POP3 TRANSACTION state machine via scripted sessions over
net.Pipe, mirroring the SMTP handler test harness: STAT/LIST/UIDL/DELE/
RETR/TOP/NOOP/RSET/QUIT including argument error paths, deleted-message
behavior, dot-stuffing, RETR/TOP source error paths, mailbox load
errors, session read error handling (idle timeout vs other), and the
TCP listener lifecycle (Start/serve/Notify/Drain).
No production code changes; current behavior is pinned as-is. Two
known RFC deviations are documented in tests (RETR/TOP of messages
marked deleted) for follow-up fixes. Package coverage: 24.4% -> 93.2%.

Refactor server life-cycle into it's own file, make service startup and monitoring more consistent and testable.
* Extract services creation in preparation for DI
* pop3: rename New to NewServer
* lifecycle: Add fatal error Notify()
* web: Introduce Server struct w/ Notify()
* Extract Start in lifecycle
* Add Start() to Hub
* RetentionScanner startup consistent with other svcs
* Remove global shutdown channel
* Implement a readiness notification system
- makefile: Don't refresh deps automatically, causes double build
- storage: Move GetMessage, GetMessages (Mailbox), PurgeMessages to the
Store API for #69
- storage: Remove Mailbox.Name method for #69
- test: Create new test package for #79
- test: Implement StoreStub, migrate some tests off MockDataStore for
task #80
- rest & webui: update controllers to use new Store methods
- All packages go into either cmd or pkg directories
- Most packages renamed
- Server packages moved into pkg/server
- sanitize moved into webui, as that's the only place it's used
- filestore moved into pkg/storage/file
- Makefile updated, and PKG variable use fixed
