Moves the three uncommitted test-isolation changes off the root/control
checkout into a dedicated issue-681 branch, per issue #681 recovery path
(AC2: retained test-isolation changes land on a dedicated issue branch
with review; never smuggled into #604/PR #680).
Preserved as-is (NOT endorsed) for review:
- gitea_mcp_server.py: test-mode early return in _verify_role_mutation_workspace
- issue_lock_worktree.py: strips *.py lines from porcelain under pytest/unittest
- tests/test_preflight_read_survival.py: patches out branches-only + root-checkout guards
These weaken workspace/dirtiness guards under test and require review before
any adoption; committed here only to restore the control checkout to clean
master without discarding unique work.

Read-only gitea_whoami calls no longer clear a valid capability proof when
whoami was already verified clean. Capability is consumed on mutation (one
resolve per mutation), and verify_preflight_purity rejects task mismatches.
