workspace/provider/model/thinking now come from getSettings() injected into
sessionRoutes; the request body supplies only question+name. Also teaches
fake_pi_rpc to respond to set_model and set_thinking_level RPC commands so
tests that pass real model settings don't hang.

POST /sessions no longer silently drops `workspace`. ThtRunner.run/json
take an optional workspace; configArg() selects workspaces/<ws>.yaml when
it exists under harnessDir, else falls back to default configPath.
sessionNew threads workspace through. Route forwards b.workspace with an
MVP note (gate/Pi side still single-workspace via symlinked config/tht.yaml).
19/19 tests pass, tsc clean.

Make buildApp injectable (deps.thtRunner + deps.spawnFn); create
src/routes/sessions.ts with all 7 session routes under authPreHandler;
wire bridge.onClientEvent→hub.publish before returning {id} from POST
/sessions; SSE subscribes with pendingWidget safety net.
18/18 tests pass, tsc clean.
