Fixes the base red in "cmux-next checks" → "Tier routing": tests/test_cmux_next_route.py test_every_routed_input_triggers_the_workflow fails with AssertionError: False is not true : .claude/settings.json.

Cause

c14a002 (the base autofix regenerating the CI target graph after #26139, "Cloud: confirmed owner-only provider credential transfer") recorded .claude/settings.json as a CmuxNextAppTests read. CloudCredentialTransferTests names home.appendingPathComponent(provider == .claude ? ".claude/settings.json" : ".codex/auth.json"), a temp home dir. literal_reads matched that literal against the repository's own tracked .claude/settings.json. The cmux-next.yml pull_request paths filter has no .claude/ pattern, so the route test, which requires every routed input to trigger the workflow, failed.

Fix

scripts/cmux-next/ci-target-graph.py literal_reads now skips .claude and .codex, the same way it already skips .git. Those directories hold the agent sessions' own config, and a test that names them means a user's home directory. Adding .claude/ to the paths filter would also turn the check green, but the whole cmux-next workflow would then run on every hook edit, for a file no Swift test reads.

The graph is bot-only (generated_outputs.py), so this PR doesn't touch it. The base autofix workflow triggers on scripts/cmux-next/ci-target-graph.py and regenerates the graph after merge. I reran literal_reads for every test target in the committed graph with this change. The only difference is that .claude/settings.json drops out of CmuxNextAppTests. Until that regeneration lands, this PR's own Tier routing step stays red, the same failure base has.

Test: tests/test_ci_target_graph.py now plants .claude/settings.json and .codex/hooks.json literals. The test fails without the fix and passes with it.

Risk: low. Only CI routing is affected. A Swift test that really read a repo file under .claude/ or .codex/ would no longer route on it, and none does today.
