Add deeper peer CLI coverage for file-transfer integrity and multi-peer
chunking. The alpha fixture now carries a real renamed RAR archive larger
than 100 MB for alienswarm, which gives the chunk planner enough work to
split a single game archive across multiple peers.
Expose completed chunk source details as a peer event and have the CLI print
that event as JSONL. This keeps transfer behavior in lanspread-peer while the
CLI remains a harness that reports what the peer runtime did. The Tauri shell
logs the event at debug level so the shared PeerEvent enum stays exhaustive.
Document the new S13/S14 scenarios and record the manual run evidence,
including SHA-256 manifests and the per-peer byte split for the large archive.
Test Plan:
- just fmt
- just test
- just peer-cli-build
- just clippy
- just peer-cli-image
- unrar t -idq crates/lanspread-peer-cli/fixtures/fixture-alpha/alienswarm/alienswarm.eti
- Manual peer CLI: bravo -> deep-small-client bfbc2 download with matching SHA-256 manifests
- Manual peer CLI: alpha -> deep-stage-b alienswarm download with matching SHA-256 manifests
- Manual peer CLI: alpha + deep-stage-b -> deep-stage-c alienswarm download with chunk events from both peers and matching SHA-256 manifests

The peer core already emits NoPeersHaveGame when a requested game cannot be
served by any known peer. The JSONL harness still waited for the generic file
detail timeout before returning the download command error, which made the
manual scenario slower and less precise.
Correlate the existing no-peers event with the pending CLI download command so
the harness returns a deterministic error immediately. This is harness
bookkeeping only; game availability and peer behavior remain owned by
lanspread-peer.
Test Plan:
- just fmt
- just test
- just clippy
- just peer-cli-build
- just peer-cli-image
- just peer-cli-alpha, just peer-cli-bravo, just peer-cli-charlie
- In charlie, send {"cmd":"download","game_id":"not-a-game"}; observe
no-peers-have-game followed by error "no peers have game not-a-game"

Add three reusable peer CLI game directory fixtures for local smoke tests.
Each fixture is a complete games root that can be passed directly to
--games-dir, with catalog-backed game IDs, version.ini sentinels, and real RAR
archives renamed to .eti.
The fixtures intentionally overlap in two places so multi-peer tests can cover
shared availability. Alpha and bravo both contain ggoo, while bravo and charlie
both contain cnc4. The archives contain generated random payload files rather
than meaningful game data; this keeps the fixtures fake while still exercising
RAR-backed ETI handling.
The tradeoff is committing roughly 34 MiB of binary fixture data. That is
intentional here because the fixtures need real archives for CLI tests instead
of synthetic text placeholders.
Test Plan:
- Ran git diff --check.
- Ran unrar t -idq over every .eti file in the fixture tree.

The peer runtime previously accepted an `enable_mdns: bool` flag, plumbed
through `PeerStartOptions`, `spawn_peer_runtime`, `run_peer`, `Ctx`, and
`PeerCtx`. The lanspread-peer-cli harness exposed the toggle as
`--no-mdns` so test scenarios could fall back to explicit `connect`
commands when mDNS could not be relied on, in particular when multiple
peers ran inside `--network host` containers and could not advertise
independently.
That host-networking workaround no longer exists: the previous commit
moves harness containers onto a macvlan network, where each peer is a
real LAN device and mDNS just works between them. There is no scenario
left in the codebase where disabling mDNS is desirable. Per the project's
protocol policy in CLAUDE.md ("there is only one wire version, no
compatibility shims, no fallback paths"), an opt-out path with no current
caller is exactly the kind of dead code we should not carry.
Remove the flag and every plumbing point that exists only to support it:
- `PeerStartOptions::enable_mdns` and the custom `Default` impl that set
it to `true`; the struct now derives `Default` and just carries
`state_dir`.
- The `enable_mdns` parameter on `start_peer_with_options`,
`spawn_peer_runtime`, `run_peer`, and `Ctx::new`.
- The `enable_mdns` fields on `Ctx` and `PeerCtx` and the propagation
through `to_peer_ctx`.
- The `if ctx.enable_mdns` guard in `spawn_startup_services`;
`spawn_peer_discovery_service` is now always spawned.
- The `if ctx.enable_mdns { ... } else { ... }` branch in
`run_server_component`: the mDNS advertiser and event monitor are now
unconditionally started, and the no-mDNS-fallback log line that read
"mDNS disabled; direct peer address is ..." is gone. The
`direct_connect_addr` helper is kept because the mDNS-on branch still
uses it as a fallback when `local_peer_addr` has not yet been
populated.
- The internal test helpers in `handlers.rs`, `services/local_monitor.rs`,
and `services/stream.rs` that passed `true` as the trailing
`enable_mdns` arg to `Ctx::new`.
- In `lanspread-peer-cli`: the `--no-mdns` arg parsing, the
`Args::enable_mdns` field, the `mdns` key on the `cli-started` event
payload, and the `--no-mdns` mention in the help text and the crate
README.
The `Args::name` field is wired to the harness identity but is otherwise
untouched. The macvlan network created by `just peer-cli-net` is the
runtime prerequisite for this change to be observable across containers;
on a single workstation, two harness binaries on `127.0.0.1` discover
each other through mDNS on the loopback interface as before.
Test Plan:
- `just fmt`
- `just clippy`
- `just test`
- `just peer-cli-build`
- Two peers on macvlan: `just peer-cli-run alpha` and
`just peer-cli-run beta`; check that each emits `peer-discovered` and
`peer-connected` events without an explicit `connect` JSONL command.

Agents need a way to exercise multiple peers without launching the Tauri GUI.
Add `lanspread-peer-cli` as a workspace crate that starts the core peer runtime,
reads JSON commands from stdin, and writes result, event, and error records as
JSONL on stdout.
The harness supports status, peer listing, game listing, direct connect,
set-game-dir, download, install, uninstall, wait-peers, and shutdown commands.
It can seed tiny fixture archives that use a fixture unpacker, or delegate real
archives to an external `unrar` program when one is supplied.
Add a Dockerfile, `.dockerignore`, and `just` recipes for building the binary,
building the image, and running named harness containers with state and games
mounted under `target/peer-cli/`. The documentation now lists the crate and the
new test harness commands in the project map, with a crate-local README for the
JSONL protocol.
This commit depends on the non-GUI peer hooks introduced in the previous commit:
startup options, local-ready events, direct connects, snapshots, and explicit
post-download install policy. It does not add old-peer compatibility paths.
Test Plan:
- `git diff --check`
- `just fmt`
- `just clippy`
- `just test`
- `just peer-cli-build`
- Not run: `just peer-cli-image` requires a Docker daemon and base image access.
