Replaces the fire-and-forget datagram path with sequenced packets, a
per-peer jitter buffer, and persistent per-peer send tasks. Together these
fix three intertwined weaknesses that only showed up off localhost.
Packet format: every audio frame now carries a 4-byte little-endian
sequence number header ([seq][opus payload]), the basis for reordering and
loss detection.
Jitter buffer (core/jitter.rs): incoming packets are reordered by sequence
behind a fixed ~60ms playout delay. Missing sequences with later packets
already buffered are concealed via Opus PLC (decode(None)) -- a path the
decoder supported but nothing ever invoked. Underruns go idle and re-buffer
rather than concealing indefinitely. Covered by unit tests using real
encoded frames (reorder, gap-conceal, prime, late-drop).
Transport (network/iroh_impl.rs): each peer gets one long-lived send task
fed by a shallow bounded channel (drop-oldest on backpressure), instead of
spawning a throwaway task per peer per 20ms frame. Connections are now
established reactively on peer-join and torn down on peer-leave; the
lexicographically-lower EndpointId dials so a full-mesh pair forms exactly
one shared bidirectional connection instead of two racing ones. This also
removes the previous lock-held-across-connect().await serialization.
Opus decoder: PLC output is now sized to one 20ms frame, so concealment
synthesizes 20ms instead of a 120ms burst from the oversized max buffer.
Known follow-up (Tier 2): no reconnect on transient connection loss; a
send error currently retires the peer until they rejoin.

- Remove Gemini's committed update_*.py regex-surgery scripts
- Drop unused iroh-tickets dependency (hand-rolled ticket is used instead)
- Replace ToString antipattern with Display impl on PeerSpeakTicket
- Route debug log to XDG state/cache dir instead of hardcoded /home path
- Clear all compiler + clippy warnings (unused imports, collapsible ifs,
redundant pattern matching, missing Default)
Builds clean with zero warnings.
