v7next F3.1 lane A: producer cutovers - core/shell/services/mcp/git and the six control rows (D05/D10/D02)

Re-derived on tip bytes; only the sanctioned publish deltas are applied, all
tip drift (deliverables lane, readiness-log machinery, roster gate, custody
params) is preserved.

- core_file_tools/core_artifacts (D05 entry 3, rows 329-349 class incl. row
  332's owner item A.20): the ten read/list/access/delivery producers publish
  their refusals and terminals through _publish_tool_result with the code the
  one adapter already assigns; A.20 adds the missing warning marker to the
  skill-owner-state refusal (the ONE text change, disclosed).
- shell_outputs._register_process_outputs (row 438): third element reports a
  CANONICAL registration; shell.py's _run_shell publishes typed process facts
  (_publish_process_result: exit_code/signal/artifact_registered/autocorrect)
  and _run_script republishes through _wrap_run_script_process_result.
- services.py (D05 entry 7c): both stop_service lanes consume the 3-tuple and
  publish ARTIFACT_OUTPUT_ERROR / OK with the artifact_registered fact.
- mcp_client.py (D05 entry 7b): adopted whole from the reference WITH BYTE
  PROOF (tip==merge-base for this file, so reference==tip+delta exactly):
  typed transport result keeps the SDK-owned error bit, host failures are
  native MCP_UNAVAILABLE/MCP_TIMEOUT/ACCESS_BLOCKED, call_tool stays the text
  projection, and provider-slug collisions surface as evidence
  (tool_name_collisions) for the registry's collision reporting.
- tools/git (D10 entry 5b, rows 394-396/410-411): _publish_git_error /
  _publish_review_blocked land in git_plumbing; _git_status/_git_diff and the
  stage cycles publish their GIT_ERROR / critical-findings REVIEW_BLOCKED
  terminals (status stays ok - same classification the loop chain gave).
- control rows 2548/2549/2556/2571/2574/2579: acting-constraint and selector
  denials publish ACCESS_BLOCKED (ctx threaded, optional for direct calls);
  _schedule_task publishes its argument/capability/drive/status refusals via
  the _publish_scheduling_refusal helper (keeps the function at its
  pre-cutover 300 lines); _get_task_result retypes the unregistered-id read
  to LEGACY_UNAVAILABLE (owner item A.21); wait_task/wait_tasks publish their
  TOOL_ARG_ERRORs.
- Carried suites, adapted per this tree (docstring disclosures):
  tests/test_core_native_results.py (minus the four IN-PLACE core.py rows
  2083-2086 - outside this lane's sanctioned row set, pending),
  tests/test_control_native_results.py (only this lane's six rows; roster
  gate seeded via tests._shared.configure_test_subagent - tip drift),
  tests/test_mcp_client.py adopted whole (tip==merge-base proof).
- Ratchet regenerated (mcp_client.py enters the band with rationale); ruff F
  clean.

producers); those clauses are NOT carried here and return with their rows.
