Neil cbf18d46d4 fix(runtime): key the wake-respawn latch per environment, like its twin
The wake-respawn latch is the initial-terminal bootstrap latch's twin — both stop
one focus from issuing two creates for a workspace, both are consulted from the
same subscription closure, and they sit one line apart in the same teardown. The
bootstrap latch got two fixes this stack; this one got neither, and still carried
both defects:

1. NOT KEYED BY ENVIRONMENT. It was a bare `Set<worktreeId>`. A worktree id is
   `repoId::path` with no host component, so the same id can be live on two
   paired runtimes at once (STA-4343) — which is exactly why the bootstrap latch
   was re-keyed. Keyed by worktree alone, one runtime's respawn suppressed the
   other runtime's, and one runtime's `end` released the other's claim.

2. A CLEAR-EVERYTHING INSIDE A PER-ENVIRONMENT TEARDOWN.
   `clearWebSessionTabsTrackingForEnvironment` called
   `clearAllWebRuntimeWakeTerminalRespawn()`, so tearing one environment down
   freed every other environment's in-flight claim and a fresh closure for the
   sibling could issue a second respawn while the first create was still running.
   That is STA-6173, and the bootstrap latch's own docstring names it: "clearing
   every environment's latch would release a sibling environment's pending create
   and let a new subscription for it seed a duplicate, which is this very bug
   through another door." The correctly-scoped bootstrap clear is the very next
   line.

Found by reading the teardown function as a list rather than as prose — a
clear-everything is a one-line call that looks identical to a scoped one at a
glance, which is how it sat next to the fix for its own defect.

Both latches now have the same shape: `Map<environmentId, Set<worktreeId>>`, a
per-worktree release, and a per-environment clear that touches only its own keys.

The existing wake-respawn test is threaded with an environment id rather than
rewritten: its contract was correct, only the signature moved. The new file
pins the two defects themselves.

Also documents `clearWebSessionTabsTrackingForEnvironment` as what it has become
— the per-environment teardown registry. It now carries seven module clears, and
a new per-environment map belongs in that list rather than behind a trigger of
its own. The doc says each clear must be scoped to THIS environment and names
the wake-respawn latch as the one that was not, because the next clear-everything
will look just as harmless.

Mutations: reverting the per-environment clear to a clear-all kills exactly the
sibling-claim assertion; making the skip check ignore the environment (the old
worktree-only keying) kills exactly the two-environments assertion and the
sibling-claim one. No survivors.
