* feat(pi): make extension result timeout configurable via provider params
* fix(acp): add tests asserting cwd and mcpServers are always passed to session/load (#1593)
Add unit tests in acp-agent.test.ts that verify initializeResumedSession()
always calls loadSession and unstable_resumeSession with { sessionId, cwd,
mcpServers } — even when mcpServers is an empty array. Some strict ACP
providers (e.g., Devin CLI) return 'Invalid params' if any of these fields
are omitted.
Also adds a docstring above initializeResumedSession() documenting this
requirement so future refactors don't accidentally drop params.
Closes#1593
* fix(acp): address Greptile review on session/load invariant tests
- Extract shared makeTestSession() factory to eliminate duplicated TestSession
class definitions across all three tests (concern #1)
- Pass handle through typed constructor option instead of casting private
initialHandle field (concern #2)
- Add missing type imports for AgentCapabilityFlags and AgentPersistenceHandle
* fix(tests): ensure ACP agent session load invariant
* fix(pi): increase default extension result timeout to 30s
