* fix(cursor): exclusive agent spawn lease for list-models vs ACP (#1520)

Add a proper-lockfile spawn lease beside agent-acp-active so model probes
and ACP transport acquire mutual exclusion atomically before spawning
agent children, closing the post-#1518 check-then-act overlap window.

Fixes #1520

* chore(web): fix markdown-a test HappyChatContext mock for typecheck

Adds showSessionSummaryInChat to chatContext() so CI typecheck passes on
the PR branch (pre-existing main breakage unrelated to #1520).

* Revert "chore(web): fix markdown-a test HappyChatContext mock for typecheck"

This reverts commit 4973f321a31fda772e8990ea6cda20517ca906aa.

* fix(cursor): scope spawn lease to agent spawn window only (#1520)

Hold agent-cli.spawn only around spawn('agent') in AcpStdioTransport, not
for the full ACP session. Restores N concurrent cursor sessions per host;
list-models probe lease unchanged.

* fix(cursor): tighten spawn lease lifecycle for babysit (#1520)

Acquire spawn lease before ACP marker publish; unregister on spawn failure.
Hold list-models probe lease until child exit on timeout. Add missing
showSessionSummaryInChat to markdown-a test mock (unblocks CI typecheck).

* fix(cursor): re-check ACP marker after spawn lease acquire (#1520)

Close check-then-act window where ACP could publish its marker between
the inactive guard read and list-models spawn. Add regression test.

* fix(cursor): async spawn lease + force-kill probe timeout (#1520)

Add acquireAgentCliSpawnLease (setTimeout yields) for ACP create path;
AcpStdioTransport.create() async factory. Probe timeout uses
killProcessByChildProcess(force) while holding lease until child exit.

Addresses Bugbot Majors: session-lifetime mutex (fe07b708d), probe lease
release, post-acquire re-check (137baa779), sync loop starvation, timeout
escalation.

* fix(acp): coalesce concurrent initialize() transport spawns (#1520)

Await shared bootstrapTransport promise so overlapping initialize calls
do not spawn duplicate ACP children while create() is in flight.
