Adds the bold-time-dash built-in pattern: **Speaker** HH:MM <dash> text
(em dash, en dash, or ASCII hyphen), valid 24-hour times only, date from
page frontmatter/date headings, multi-line continuation bodies.
Opt-in score_continuations_as_body scoring keeps long multiline messages
parseable while preserving the sparse-prose false-positive floor (needs
two anchors or a first-line anchor before candidate-only scoring kicks in).
Hardens validatePatternEntry to reject non-integer / out-of-range capture
indexes including text_group. Adds maintainer doc, JSONL fixtures, and
adversarial coverage.
Takeover of #3289 (fork branch went CONFLICTING against master on the
version trio); code applied 3-way, version/CHANGELOG bump dropped per
fleet release convention.
