- Re-prompt path calls _strip_tool_markup(final=True) on content_accum
before measuring intent / artifact / length. An orphan
``<tool_call>...</tool_call>`` block containing a code fence no
longer hides the intent-only visible answer from the artifact check.
- _DIRECT_NUMBERED_PLAN_FRAMING splits into two branches:
* First-person intent ("I'll", "Let me", "I will", etc.) accepts a
broader work-verb set (open, read, search, check, review, inspect,
examine, etc.). Direct first-person announcements are strong
plan-like signals.
* Bare "First, ..." / "Step N: ..." keeps the narrow verb set so
algorithmic answers ("First, use binary search:") stay valid.
Catches stalls like "I will check the docs:\n1. Gather..." and
"Let me read the uploaded file:\n1. Identify the columns..." that
previously slipped past the freshness-gated lookup verbs.
