resolve_canonical_repo_root fallback now uses commonpath only — no
string split and no os.path.isdir gate — so MCP project_root =
branches/<wt> still resolves to the repo root when the path is not yet
on disk (#274 / review #551 regression).
Author mutation tools now resolve workspace via explicit worktree_path,
env bindings, or the active author issue lock — never silent fallback to
the control checkout/master. Missing configured bindings fail closed with
operator recovery; create_issue and create_issue_comment agree.
Recovered onto 0568f44 from preserved candidate cbf56ccd (AUTHOR_RECOVERY).

Merge prgs/master into feat/issue-274-branches-only-worktrees; keep both
already_landed_reconcile and author_mutation_worktree imports. Allow
branches/ worktrees when PROJECT_ROOT is the session worktree; align
commit-payload tests with branches-only guard (#274).
Add author_mutation_worktree assessment and integrate it into MCP
preflight so author mutations fail closed outside branches/ session
worktrees, with tests for control-checkout and branches-path cases.
