Wires the workspace handshake end to end so a session's workspace is bound
from the client's cwd at connect time and is event-sourced for replay.
- Go TUI sends Hello{workingDir=os.Getwd()} as the first WS frame on connect
(protocol.go encoder + client.go connect path; golden test pins the wire
format against the Kotlin discriminator).
- Server adds ClientMessage.Hello, stashes the per-connection workingDir, and
on session start resolves it through WorkspaceResolver's trust pipeline,
emits SessionWorkspaceBoundEvent (invariant #9), and threads the resolved
workspace into OrchestrationConfig for the live run. A Hello after the first
StartSession is ignored (warn); a rejected path binds the resolver fallback.
- Replay derives the workspace from the recorded event: SessionState gains
boundWorkspace, DefaultSessionReducer fills it from SessionWorkspaceBoundEvent,
and ReplayOrchestrator uses it (Path.of only, no filesystem re-query —
invariant #8) with graceful fallback to config for pre-Phase-B logs.
Absent Hello / null resolver degrades to the prior config-workspace behavior.
