Subject: [ANNOUNCE] TinyMUX 2.13.0.13 BETA released

TinyMUX 2.13.0.13 BETA is now available. This release contains
Unicode correctness fixes, significant performance improvements
to Unicode normalization and collation, and a SQLite write-through
optimization.

Changes since 2.13.0.12 BETA
- ------------------------------

  Bug Fixes:

  - Fixed NFC over-composition and DUCET contraction false-matches.
    The pairs DFA generator was not resolving undefined transitions
    before optimization, causing incorrect results. NFC compose
    tables regenerated (129 to 1010 states) and DUCET contraction
    tables regenerated (27 to 294 states).
  - Fixed collation NFC tiebreaker. Strings are now normalized to
    NFC before binary comparison so that canonically equivalent
    strings compare equal per UCA.
  - Restored timezone prefetch probes that were inadvertently
    disabled.

  Performance:

  - Disable WAL auto-checkpoint for SQLite write-through. Eliminates
    per-transaction fsync from the hot path; explicit checkpoint at
    @dump and shutdown.
  - Combined CCC+NFCQC DFA: merged two separate DFA lookups into
    one, eliminating a full DFA traversal per non-ASCII codepoint
    in NFC quick-check and normalization.
  - Collation performance improvements backported from libutf:
    Latin CE cache for U+0000..U+017F (single lookup, no DFA),
    ASCII byte-skip in FastLatinCmp, CJK inline implicit weights,
    bounded CE collection with overflow fallback, fast
    case-insensitive Latin sort keys, and buffered level
    comparisons for medium-length strings.

  Other:

  - Updated table generator tools (classify, integers, strings,
    pairs) to support -o/-i flags for output file control.
