fix(#1156): support table-format STATE.md and insert missing roadmap plan rows (#1172)

* fix(#1162): support table-format STATE.md in state field read/replace

Extend stateExtractField and stateReplaceField in state-document.cts to
detect and operate on pipe-table rows (| Field | value |).  The separator
row | --- | --- | is excluded from matching.  updateCurrentPositionFields
in state.cts now falls through to stateReplaceField for table-format
Current Position sections when the inline Status:/Last activity: patterns
do not match.

* fix(#1163): insert missing plan checklist rows in roadmap update-plan-progress

cmdRoadmapUpdatePlanProgress now inserts `- [ ] NN-XX-PLAN.md` checkbox
rows under the phase Plans: line when no per-plan checkbox rows exist yet
(fresh template).  Rows are sorted ascending and any already-summarised
plans are immediately marked [x].  The planCountPattern is extended to
also match plain `Plans:` (in addition to bold `**Plans:**`) so plan
counts are updated in both template variants.  The existing-rows check
covers both top-level and indented checkbox forms to preserve idempotency.

* fix(#1163): fill partial plan-row gaps and scope insertion to active milestone

- Finding 1 (HIGH): replace all-or-nothing rowsAlreadyPresent guard with per-file
  set-difference so missing rows are inserted even when SOME plan rows already exist
- Finding 2 (MEDIUM): extend planCountPattern to recognise **Plans**: (canonical
  template form — bold word + outer colon) alongside **Plans:** and plain Plans:;
  use two-pattern fallback for row insertion to anchor under Plans: checklist header
  rather than the **Plans**: summary line
- Finding 3 (MEDIUM): scope row insertion to the active (post-</details>) milestone
  region so duplicate phase headings in archived sections never receive new rows
- Finding 4 (LOW): rename misleading "pipe-like content" test to honestly describe
  what it tests (multi-row table isolation); add out-of-scope escaped-pipe comment
- Remove now-unused anyCheckboxMatched variable (lint clean)
- Add 5 adversarial regression tests (pre-fix failures confirmed)

* fix(#1163): scope missing-plan detection to active milestone; preserve authored state fields in table format

- roadmap.cts: compute activeRegion (post-</details> slice) once and use it
  for BOTH missingPlans detection and row insertion, so archived <details>
  rows no longer suppress active-section inserts (Finding 1 code-review)
- roadmap.cts: change (Plans:) inner capture to non-capturing (?:Plans:)
  in insertRowsPatternA to prevent group-numbering shift (Finding 3)
- state.cts: mirror inline-branch preserve-authored guards onto table-format
  branches in updateCurrentPositionFields — Status table branch checks
  isInList/matchesPattern before replacing; Last Activity table branch
  checks isDateShape/inList, preserving executor-authored narrative prose
  (Finding 2 code-review)
- tests: add three failing-first regression tests confirming each finding

* test(#1162,#1163): fold table-format + plan-row regressions into owning module tests

Move bug-1162 cases into tests/state.test.cjs and bug-1163 cases into
tests/roadmap.test.cjs under named regression describe blocks; delete the
standalone bug-NNNN files and prune their allowlist entries.
