fix(queue): use label= (singular) not labels= (plural) for Gitea 1.22.6 API

Gitea 1.22.6's /repos/{R}/issues endpoint accepts `label` (singular)
for filtering by a single label name, not `labels` (plural). Using the
wrong param silently returns 0 results, so the queue cron has been
picking no PRs for every tick.

Fixes the merge queue silently returning 0 queued PRs.

- *  - openclaw → `/agent-home` (the agent's identity/state — the
- *    user-facing interesting files for that runtime live in
- *    `~/.openclaw/` inside the container, which `/agent-home` maps to
- *    via the Phase 2b docker-exec backend).
- *  - everything else (claude-code, hermes, external-like, undefined)
- *    → `/configs` (the legacy default — managed config that flows
- *    through the per-runtime indirection in
- *    workspace-server/internal/handlers/template_files_eic.go).
- *
- *  When the runtime is undefined (legacy callers that don't thread
- *  `data` through, or a workspace whose runtime field hasn't loaded
- *  yet) the default is `/configs` — matches today's behaviour, no
- *  surprise.
- *
- *  Note on `/agent-home` pre-Phase-2b: the backend short-circuits
- *  with HTTP 501 and the canonical "implementation pending" body.
- *  The tab renders empty + the error banner explains. This is by
- *  design — lets us land the canvas UX before the backend ships,
- *  per the RFC's phased rollout. The 501 is graceful: it doesn't
- *  poison error toasts or generate "workspace not found" noise.

 ### broadcast_message
 Use for urgent, org-wide signals: critical status changes, emergency stop instructions, coordinated task announcements. Every non-removed workspace receives the message in its activity log (poll-mode agents see it on their next poll; push-mode canvases get a real-time banner). This tool returns an error if broadcast_enabled is false — a user or admin must enable it via the workspace abilities settings first.

+"""OFFSEC-003 regression backstop — sanitize_a2a_result invariant across all A2A tool exit points.
+
+Scope
+-----
+Every public callable in ``a2a_tools_delegation`` that returns peer-sourced content
+must pass its output through ``sanitize_a2a_result`` before returning to the agent
+context.  These tests inject boundary markers and control sequences from a
+mock-peer response and assert the returned value is the sanitized form.
+
+Test coverage for:
+  - ``tool_delegate_task``            — main sync path
+  - ``tool_delegate_task``            — queued-mode fallback path
+  - ``_delegate_sync_via_polling``    — internal polling helper
+  - ``tool_check_task_status``        — filtered delegation_id lookup
+  - ``tool_check_task_status``        — list of recent delegations
+
+Issue references: #491 (delegate_task), #537 (builtin_tools/a2a_tools.py sibling)
+
+Key sanitization facts (for test authors):
+  • _escape_boundary_markers: replaces "[A2A_RESULT_FROM_PEER]" with
+    "[/ A2A_RESULT_FROM_PEER]" and "[/A2A_RESULT_FROM_PEER]" with
+    "[/ /A2A_RESULT_FROM_PEER]". The escape form is "[/ " (bracket-space).
+    Assertion pattern: assert "[/ A2A_RESULT_FROM_PEER]" in result.
+  • Defense-in-depth injection escape patterns replace SYSTEM/OVERRIDE/
+    INSTRUCTIONS/IGNORE ALL/YOU ARE NOW with "[ESCAPED_*]" forms.
+  • Error path: when peer returns an error-prefixed string (starts with
+    _A2A_ERROR_PREFIX), the raw error text is included in the user-facing
+    "DELEGATION FAILED" message. This is intentional — errors from peers
+    are surfaced as errors, not as sanitized results.

-"""Tests for ``tool_get_runtime_identity`` and ``tool_update_agent_card``.
-
-These two MCP tools close the T4-tier workspace owner-permission gaps
-reported via the canvas:
-
-  - the agent could not update its own ``agent_card`` (no MCP tool
-    wrapped the existing ``POST /registry/update-card`` endpoint);
-  - the agent could not identify which model it was running (the
-    ``MODEL`` env var is injected by ``provisioner.workspace_provision``
-    but nothing surfaced it back to the agent).
-
-Ported from molecule-ai-workspace-runtime PR#17 (mirror-only repo;
-canonical edit point per ``reference_runtime_repo_is_mirror_only``).
-Adapted to core's conventions:
-
-  * tool functions return ``str`` (JSON-encoded), matching every other
-    tool in ``a2a_tools_*`` modules. Tests ``json.loads`` to inspect.
-  * permission check ``memory.write`` runs inline in
-    ``tool_update_agent_card`` (same pattern as
-    ``a2a_tools_memory.tool_commit_memory``).
-  * ``WORKSPACE_ID`` is read directly from ``os.environ`` — core does
-    not have the runtime's validated-cache layer (``molecule_runtime.
-    builtin_tools.validation``).

-Covers provider routing, URL-override precedence, and the missing-key error path.
-Each adapter defines its own registry; this test file defines one inline that
-mirrors what the openclaw adapter uses.
+The key-selection and URL-routing logic lives inline in OpenClawAdapter.setup()
+(adapter.py lines 84-92).  Since setup() carries heavy subprocess dependencies,
+these tests isolate the selection logic by reproducing the exact Python expressions
+from the adapter source — if the adapter's logic changes, these tests must be kept
+in sync.

+Organisation:
+  TestEnvKeyChain          — priority order of the 3 currently supported keys

+  TestNegativeAndFallback  — no keys set / unsupported keys
