fix: semver 3+ segment parsing and CRLF frontmatter corruption recovery

- fix(core): getMilestoneInfo() version regex `\d+\.\d+` only matched
  2-segment versions (v1.2). Changed to `\d+(?:\.\d+)+` to support
  3+ segments (v1.2.1, v2.0.1). Same fix in roadmap.cjs milestone
  extraction pattern.

- fix(state): stripFrontmatter() used `^---\n` (LF-only) which failed
  to strip CRLF frontmatter blocks. When STATE.md had dual frontmatter
  blocks from prior CRLF corruption, each writeStateMd() call preserved
  the stale block and prepended a new wrong one. Now handles CRLF and
  strips all stacked frontmatter blocks.

- fix(frontmatter): extractFrontmatter() always used the first ---
  block. When dual blocks exist from corruption, the first is stale.
  Now uses the last block (most recent sync).
