molluskandClaude Opus 4.8 d0a16cb8b9 style: apply cargo fmt across the crate (A20)
The repo never enforced rustfmt, so formatting had drifted broadly. This is a
single mechanical `cargo fmt` pass over the whole crate (no behavioral change;
lib suite green, 493 passed). Going forward fmt should be enforced (planned CI
fmt --check step). Part of the 0.6.1 hygiene pass.

molluskandClaude Opus 4.8 efadc228eb fix(files): keep serve connection alive until fetcher has the bytes
windows-build / windows-build (push) Has been cancelled
cargo-deny / cargo-deny (push) Has been cancelled
Chat file fetches failed 100% of the time with "file fetch: read failed:
read error: connection lost" (both images and arbitrary files, both
directions). Root cause: the FileRouter serve handler called send.finish()
and immediately returned Ok(()), which dropped the Connection. In QUIC,
finish() only marks the stream's EOF -- it does not wait for the written
bytes to be delivered and acknowledged -- so the connection's
CONNECTION_CLOSE raced ahead of the still-in-flight stream data and the
fetcher's read_to_end aborted.

Fix: after finishing, wait on connection.closed() (bounded by
FILE_FETCH_TIMEOUT) so the link stays up until the fetcher has read
everything and closed the connection itself, which is the signal the
transfer landed.

Wire-compatible (no protocol change), so version stays 0.3.0; both peers
just need the rebuilt binary since either side can be the file server.

Adds tests/file_transfer_loopback.rs: a real two-endpoint serve->fetch
round-trip over FILES_ALPN with a 2 MiB multi-packet blob (deterministic
A/B: 0/20 pass without the fix, 20/20 with it) plus an unknown-id "gone"
case.
