fix(bootstrap): allow author worktree bootstrap from clean control checkout (Closes #892)

Align assess_author_issue_bootstrap with bootstrap_permits_control_checkout
so gitea_bootstrap_author_issue_worktree can create the first branches/
worktree without the lock↔worktree deadlock.

-### 4. Review-State Invalidation on Profile Switch (#690)
-
-A cross-profile activation (e.g. reviewer → author → reviewer) is a session
-boundary for formal review state. On any switch where the activated profile
-differs from the previous one, `gitea_activate_profile` invalidates, in
-memory **and** in durable session state (for both the old and new profile
-identities):
-
-- preflight identity/capability stamps (`gitea_whoami` / `gitea_resolve_task_capability` proof),
-- review workflow-load proof (`gitea_load_review_workflow`),
-- the review decision lock (including `final_review_decision_ready` markers),
-- the reviewer PR session lease binding,
-- live namespace-health assessments.
-
-Before any formal verdict (`gitea_mark_final_review_decision` /
-`gitea_submit_pr_review`) the full reviewer preflight must be re-established
-under the new profile: `gitea_whoami`, `gitea_load_review_workflow`,
-`gitea_resolve_task_capability(review_pr)`, live head re-pin, and lease
-re-acquire/adopt. Switching back to the earlier profile does **not**
-resurrect the prior run — durable state keyed by either profile identity is
-cleared at switch time.
-
-The supported pattern remains **separate session/namespace per role**
-(dual-namespace, §2): file author-side follow-ups from an author session,
-not by hopping profiles inside a formal review run. Runtime profile
-switching is the operator-approved exception and always carries the
-re-preflight cost above.
-
-### 5. Namespace Provenance (#690)
-
-The server cannot derive its own client-managed MCP namespace name, so a
-launcher may declare it via the `GITEA_MCP_NAMESPACE` environment variable
-(e.g. `gitea-reviewer`). `gitea_whoami`, `gitea_get_runtime_context`, and
-`gitea_resolve_task_capability` report `namespace_provenance` — the
-configured client namespace, the active execution profile, and, for tasks
-with a required namespace (`review_pr` → `gitea-reviewer`, `merge_pr` →
-`gitea-merger`), a mismatch verdict. A declared namespace that disagrees
-with the requested task's required namespace **fails closed**. An
-undeclared namespace is reported as `unknown` and is never treated as
-proof either way.

+"""Regression: author worktree bootstrap from clean control checkout (#892).
+
+#892 is the four-door deadlock where every documented recovery path is closed:
+bootstrap refuses control, lock demands an existing worktree, worktree-start
+demands a lock, and shell worktree add is outside the sanctioned MCP path.
+
+Root cause: assess_author_issue_bootstrap returned allowed/proven for a clean
+control checkout, but bootstrap_permits_control_checkout only accepted
+create_issue assessments (task_scope=create_issue_only + empty reasons + full
+base-tip field set). Author assessments never satisfied the shared predicate,
+so the #274/#604 guards kept the ordinary control-checkout block.
