Adds `SessionView { Terminal, Structured }` to maestro-protocol, a
defaulted `view` field on `Session` and `CreateSessionRequest`, and
sidecar round-trip tests for both a legacy payload with no `view` key
and a `Structured` session. Nothing reads the field yet; every other
struct literal across the workspace picks up `Default::default()`
(Terminal) to keep compiling.

//! The performance contract of #83: the blocked-work pass must cost NO git
|
|
//! probe at all for a session without a worktree, while a session with one is
|
|
//! still probed.
|
|
//!
|
|
//! `git` itself is shimmed through PATH with a wrapper that logs every
|
|
//! invocation before exec'ing the real binary, so the assertion counts actual
|
|
//! probes rather than inferring them from state. This lives in its own test
|
|
//! binary because it mutates the process environment.
