feat: TA-Lib candlestick patterns — hikkake-mod/pigeon/neck-lines (part 5 of 9) (#137)

* feat: add hikkake-modified, homing-pigeon and neck-line candlestick patterns

Five patterns, all `Input = Candle`, `Output = f64`:

- Modified Hikkake (CDLHIKKAKEMOD) — a close-confirmed Hikkake: an inside bar
  then a breakout that closes back inside the inside-bar range; bullish +1,
  bearish -1.
- Homing Pigeon (CDLHOMINGPIGEON) — two black candles, the second a small body
  inside the first, a bullish reversal; +1.
- On-Neck (CDLONNECK) — long black bar then a white bar closing at its low (the
  neckline), a bearish continuation; -1.
- In-Neck (CDLINNECK) — long black bar then a white bar closing just into its
  body, a bearish continuation; -1.
- Thrusting (CDLTHRUSTING) — long black bar then a white bar closing well into
  but below the midpoint of its body, a bearish continuation; -1.

Counter 264 -> 269 (mod-count == lib counted block; FAMILIES total 259 -> 264).

* chore: sync indicator count to 269
