Summary

Base red: CmuxNextAppTests doesn't compile on feat-cmux-next, so no Swift test suite of the CmuxNext package can run. The cause is a semantic merge break between two PRs:

• cmux-next: wire explicit read-only remote agent observation #21258 (cc6fde5) made isReadOnly a requirement of AgentSessionRemoteClient.
• cmux NEXT: show and open a Cloud VM chat's child chats #23163 (c2b90f6), merged after it, added RemoteChildSessionsTests.FakeClient without that property.

The fake stands in for a writable daemon attachment, so it now declares let isReadOnly = false.

Testing

• Red: a fleet run-swift-testing-suites.sh Packages/macOS/CmuxNext run on base 4a6ef5b fails to build: RemoteChildSessionsTests.swift:14:37: error: type 'RemoteChildSessionsTests.FakeClient' does not conform to protocol 'AgentSessionRemoteClient' (note: protocol requires property 'isReadOnly').
• Green: the same fleet run on this head (46916d2) gets through build-and-list (233 s), compiles CmuxNextAppTests RemoteChildSessionsTests.swift with no error, and starts the suites.

Observed / Not run

Observed: the red and green fleet builds above. Review: an independent review subagent passed it. It confirmed isReadOnly was the only missing requirement, and that false changes no assertion: these tests only send _acpmux/watch, which never reads the flag. It also confirmed the other two conformers already declare it.

Not run: I merged before the fleet suite run finished, so the suites' results aren't in yet.

Red on this head that isn't this PR's: cmux-next checks fails on Companion workflows, because scripts/cmux-next/base-autofix-repair.sh doesn't exist in that job. That's a workflow-script problem; this PR changes one Swift test file.

Not verified: macOS jobs did not run: compile and app tests were skipped on 46916d21b0; ci-status is green without them.

CI passes on 46916d21b0 (run 39595132058 attempt 1).
macOS jobs did not run: compile and app tests were skipped: Fast static checks skipped (the macos job needs both to succeed). Re-run CI once they pass, before merging.

Written by scripts/ci/classify_failures.py (ci-failure-attribution.yml); signatures are its SIGNATURES table. A machine verdict is the runner's fault, not this PR's; yours means the failing file is one this PR changes, also red on main that main's latest full suite fails the same way, seen on other PRs that it failed on another pull request's run lately.

red: cmux-next checks (god files, concurrency, crash safety, l10n); no finished base run on f90fbd9 to compare; do not merge until green; see lane-rules
