Daniel Han d38bb3f077 Studio: revert Plan: / "Here is the plan" intent and narrow plan verbs
Reviewer round 9 (5 of 10 reviewers) flagged that the new bare
``Plan:`` / ``Approach:`` / ``Here is the plan`` intent branches
reintroduced the original "wipe a complete answer" failure for
realistic final answers whose topic happens to contain a tool-action
word. Triggers for prompts like "Create a lesson plan for teaching
search skills" when the model answers:

  Plan:
  1. Search skills: students learn query keywords.
  2. Source evaluation: compare domains.
  3. Reflection: write what worked.

``_INTENT_SIGNAL`` matched the new ``Plan:`` lookahead because
``search`` appears within 120 chars, then ``_PLAN_LIST_FRAMING``
disqualified the numbered list, and the synthetic STOP turn wiped a
valid answer.

Revert the additions in ``_INTENT_SIGNAL``:
  * Drop ``Plan:`` / ``Approach:`` (newline + action-verb lookahead).
  * Drop ``Here is the plan`` / ``Here are my steps`` (action-verb
    lookahead).

Plan stalls phrased with explicit first-person intent ("I'll search...",
"First, I'll fetch...", "Let me look up...") are still caught by the
existing intent patterns and ``_PLAN_LIST_FRAMING``.

Also narrow the plan-list action-verb whitelist to tool-specific verbs
(``search`` / ``look up`` / ``fetch`` / ``browse`` / ``web search`` /
``call (a) tool`` / ``run python`` / ``execute python``). Broad verbs
like ``use`` / ``compare`` / ``check`` / ``find`` / ``think`` /
``respond`` / ``answer`` / ``analyse`` / ``explore`` / ``outline`` /
``reason`` are removed because real answer lists use them ("1. Use
BFS", "1. Compare versions").

Finally, fix the test module's ``loggers`` / ``structlog`` stub
injection to only fire when the real module is missing AND to set
``__path__ = []`` on the stub. Previously the bare ``ModuleType`` could
poison ``sys.modules`` for any later test that imports a real
submodule (``from loggers.handlers import ...``).

Net behavioural change vs the previous commit: stricter on what
counts as a plan stall, never wipes a final answer titled
``Plan:`` / ``My plan:`` / ``Here is the plan you asked for``.
