feat(install): stamp username into account_name.txt after install

Some games ship an `account_name.txt` file somewhere under the unpacked
`local/` tree (location varies per game). After install or update, write
the configured username into the first such file we find so the game
launches under the user's account instead of whatever default the
archive contains.

The search is a deterministic alphabetical DFS rooted at the install
staging dir (`.local.installing/`, which becomes `local/` on rename),
stopping at the first regular-file match. Symlinks named
`account_name.txt` are skipped (`is_file()` is false for symlinks on
Linux), so a hostile archive can't redirect the write outside the game
tree. If no `account_name.txt` exists anywhere in the install, the step
is a no-op. If the write fails, the existing install rollback (cleanup
of staging on fresh installs, restore from backup on updates) handles
it — no partial state is left behind.

The username flows from the Tauri layer, where it is already sanitized
by `sanitize_username`, down through `PeerCommand` variants
(`InstallGame`, `DownloadGameFiles`, `DownloadGameFilesWithOptions`)
into `install`/`update`, which now take an `Option<&str> account_name`.
For the "install game that isn't downloaded yet" path the username has
to bridge the async gap between the `GetGame` / `FetchLatestFromPeers`
request and the eventual `GotGameFiles` event; we park it in a
per-game-id map on `LanSpreadState` and pop it when forwarding the
download command. The map is also cleared defensively on
`cancel_download`, `DownloadGameFilesFailed`, and
`DownloadGameFilesAllPeersGone` so a stale entry can't bleed into a
subsequent install with a different username.

`PeerCommand` is the in-process command channel, not the wire protocol;
no on-wire types changed, so the "one wire version" policy is
preserved. The peer-cli harness keeps passing `account_name: None`
since it tests peer interop, not user-facing settings.

# Test Plan

Unit tests in `crates/lanspread-peer/src/install/transaction.rs`:
- `install_overwrites_first_account_name_file` — unpacker creates
  `a/account_name.txt` and `z/account_name.txt`; after install with
  username "Alice", `a/` is overwritten and `z/` is left untouched,
  pinning the sorted-DFS "first match wins" behavior.
- `install_account_name_missing_file_is_noop` — install with a
  username but no `account_name.txt` anywhere in the archive
  succeeds and creates no spurious file.

Manual GUI check: in Settings, set a username; install a game whose
archive contains `account_name.txt`; open `local/` and confirm the
file now holds the configured username. Repeat for the update flow
(install, change username, click update).

lanspread-peer-cli

Scriptable peer harness for automated LAN-spread tests. The binary starts the core peer runtime without the Tauri GUI, reads one JSON command per stdin line, and writes JSONL events, results, and errors to stdout.

Running

just peer-cli-build
just peer-cli-image
just peer-cli-run alpha

Useful flags:

--games-dir PATH stores local archives and installs.
--state-dir PATH stores the generated peer identity.
--fixture GAME_ID seeds a tiny archive that the fixture unpacker can install.

Fixture Game Directories

fixtures/fixture-alpha, fixtures/fixture-bravo, and fixtures/fixture-charlie are ready-to-use game directories for local CLI smoke tests. Point --games-dir at one of them to start a peer with several catalog-backed fake games. Each game includes version.ini and a real RAR archive renamed to .eti; fixture-alpha and fixture-bravo share ggoo, while fixture-bravo and fixture-charlie share cnc4.

Commands

Every command is a JSON object with cmd or command; id is optional and is echoed back on the result or error line.
