v0.4.1 — README feature docs

Documentation only. The README now documents all v0.4.0 features (speak/lottery/phone/thai_id/percent/short/qualifiers/idioms/extract/parse options/rounding/money subpackage/CLI). No code changes since v0.4.0.

v0.4.0 — full parity with thainum.dart 0.5.3

New modules: speak (digit reading) · lottery · phone · thai_id (mod-11 checksum) · percent · short (abbreviated magnitudes) · qualifiers · idioms · money subpackage (typed Baht/Satang/BigInt).

parse family: ExtractNumbers · ParseDecimal · parse options (Strict/Lenient/AllowColloquial) · IsDigits.

money/rounding/CLI: SatangRounding (5 modes) on BahtFromString · cmd/thainum CLI (spell/baht/parse/digits/date).

See CHANGELOG for the full list.

• FormatDuration — วัน/ชั่วโมง/นาที/วินาที

v0.2.0

Adds:

• Ordinals — Ordinal(n) (ที่…)
• Fractions — Fraction(num,den) (เศษ…ส่วน…)
• Buddhist-Era years — Year(be) (พุทธศักราช…) + CEToBE/BEToCE
• SatangFromFloat(float64) int64; BahtFromFloat now routes float→satang→BahtSatang

All new helpers are also Speller methods (EtMode-aware).

v0.1.0

Initial release — Thai number toolkit: numerals (๐-๙↔0-9), number→Thai words (incl. decimals, big, EtMode), Thai Baht text, money/number formatting, and reverse parsing (words→number). Pure Go, dependency-free core + optional decimaladapter.
