v14.4.1

Patch. v14.4.0 was tagged while the qs_browser test layer was red — the
Phase DK/DL overnight refactors had fallout that an exit-247 watchdog
hang was masking. This cut fixes the user-facing App2 bugs that surfaced
and stabilizes the CI suite. No new features.

Fixed — App2 (self-hosted dashboards)

• Literal ' in descriptions. Sheet/visual descriptions with a
  quoted code span (e.g. L1 Pending Aging's `status='Pending'`)
  rendered a literal ' instead of '. _render_inline_markdown
  over-escaped the apostrophe with html.escape(quote=True) before the
  markdown pass, which python-markdown then re-escaped inside the code
  span. Fixed via quote=False (prose is text content, never an HTML
  attribute). The DK.11 literal-entity scanner now also pierces
  <code>/<pre> for the quote family so a recurrence fails a test.
• Cross-sheet drills widen the destination date window again. Drilling
  "View Transactions for this transfer" (Pending / Unbundled Aging,
  Supersession Audit → Transactions) onto an OLD transfer landed on an
  empty table — App2 was dropping the drill's DrillStaticDateTime
  date-widen writes (the assumption "App2's date filter defaults to all
  rows" went false at the DK data-anchor refactor). App2 now applies
  static-value drill writes, restoring App2↔QS parity.

Test / CI stabilization (Phase DP)

• Picker anchors + drill guardrails now exercise VALID rows instead of
  _spine_plant planted-error markers (which surfaced as picker anchors
  and drill rows after DL.3's marker sweep), eliminating the exit-247
  hang that had painted main red since the v14.4.0 cut.
• The QS embed driver's empty-state read converts from a fixed 800ms
  one-shot to a bounded paint-poll, fixing the flaky
  dropdown_pickers_inverse_excludes_anchor[qs-*] restore step under
  concurrent-worker load.

(The original DL.3 leaf-drift → Daily-Statement picker-shape fix — drill
writing account_id vs the picker's account_display — shipped in
v14.4.0; v14.4.1 fixes the regressions the same overnight sweep layered
on top, now guarded by the parametrized cross-sheet-drill suite.)
