mavend seals its encrypted database in `defer st.Close()` when run() returns.
It had not returned since 2026-07-21. Every restart since then decrypted the
same eleven-day-old ciphertext and rolled back everything written in between:
the Telegram nudge that kept firing was a fact being un-written on each boot.
The goroutine dump named it. main → srv.Close() → ipc.(*Server).Close →
wg.Wait(), waiting on per-connection goroutines parked in readFrame. Close
shut the listener and nothing else, so the idle persistent sockets held by
mavweb, mavpoll, mavcaldav and mavmaild blocked shutdown forever. `docker
compose stop -t 60` spent the whole sixty seconds and then took a SIGKILL.
So: track the accepted conns and close them, in ipc and in voice, which had
the identical defect. Bound all three waits — the two per-server ones and the
worker wait in main — because the seal matters more than any single in-flight
call. A dropped RPC costs one reply; a missed seal costs a session.
The regression test leaves a client connected and idle, which is the case the
old tests avoided by closing the client first.

Two spine infra items (feature-ranking #1, part of the migration prereq):
- migrations.go: PRAGMA user_version runner, empty (no-op) migration slice,
one tx per step, fail-closed. Mechanism in place before any real schema
change needs it.
- crypt.go: file-level at-rest encryption. On-disk file is always AES-256-GCM
ciphertext; decrypted to a tmpfs working copy modernc sqlite operates on;
re-encrypted atomically on Close, plaintext wiped, key zeroed. Pure stdlib,
CGO stays off. Fails closed on wrong key/tamper, never falls back to
plaintext. Key is a 32-byte seam (config db_key_b64/db_key_env today; the
passkey-derived L3 cold-start key plugs into the same seam later).
Chosen over cgo SQLCipher (would force libsqlcipher + CGO across the project)
and over the ncruces page-level VFS (swaps the driver project-wide); noted as
the upgrade path in a ponytail: comment. Threat model is disk-at-rest only.
