refactor(sync): launcher sync command proxies to the app's --sync-cli

The engine now executes only inside the app (libsql): subminer sync
rebuilds the equivalent --sync-cli argv and spawns the discovered app
binary with the terminal attached (stdin for ssh prompts, raw NDJSON
stdout, exit-code passthrough). The bun:sqlite driver binding and the
launcher-side engine shims are gone; flow tests moved to
src/core/services/stats-sync/sync-flow.test.ts, ssh tests to src, and
the merge suite now runs through the libsql driver the app ships.

## Unreleased
**Added**
- Stats Sync Without the Launcher: The stats sync engine now runs inside the app. The sync window no longer needs bun or the `subminer` command-line launcher installed, and a remote machine only needs SubMiner itself — the app answers `SubMiner --sync-cli sync ...` headless (works over SSH with no display), and remote lookup finds the app binary or the launcher automatically.
- Stats Sync Without the Launcher: The stats sync engine now runs only inside the app. The sync window and the `subminer sync` command both delegate to `SubMiner --sync-cli` (headless, works over SSH with no display), so neither machine needs bun or the command-line launcher — a remote machine only needs SubMiner itself, found automatically as the app binary or via the launcher proxy.
- Stats Sync With Windows Remotes: Sync now detects the remote shell (POSIX, cmd, or PowerShell) and manages remote temp files through SubMiner itself (`sync --make-temp`/`--remove-temp`) instead of `mktemp`/`rm`, so a Windows machine with the built-in OpenSSH Server works as a sync remote; SubMiner is found in its default Windows install location automatically.

## Sync Between Machines
`subminer sync <host>` merges immersion stats and watch history between two machines over SSH, so both end up with the union of sessions, lifetime totals, vocabulary counts, daily/monthly charts, and `--history` entries. `<host>` is anything `ssh` accepts (`user@hostname` or an ssh config alias); SubMiner must be installed on both machines at the same version. The command-line launcher is optional on both sides: the app itself answers sync commands (`SubMiner --sync-cli sync ...`), the sync window runs the engine in-app, and the remote side is found automatically whether it has the launcher or just the app.

The sync engine runs only inside the app (`SubMiner --sync-cli sync ...`): the sync window spawns it that way, `subminer sync` is a thin proxy that forwards to the installed app, and the remote side is found automatically whether it has the launcher or just the app — so the command-line launcher is optional everywhere.
