feat(pattern_recognitions): add 25 remaining Cdl* candlestick pattern wrappers

Browse Source 
Complete the TA-Lib candlestick pattern recognition coverage by adding the second
half of the Cdl* function family.

New functions in pattern_recognitions.go (all return []int32, OHLC inputs):
  CdlLadderBottom, CdlLongLeggedDoji, CdlLongLine, CdlMarubozu,
  CdlMatchingLow, CdlMatHold(penetration), CdlMorningDojiStar(penetration),
  CdlMorningStar(penetration), CdlOnNeck, CdlPiercing, CdlRickshawMan,
  CdlRiseFall3Methods, CdlSeparatingLines, CdlShootingStar, CdlShortLine,
  CdlSpinningTop, CdlStalledPattern, CdlStickSandwich, CdlTakuri,
  CdlTasukiGap, CdlThrusting, CdlTristar, CdlUnique3River,
  CdlUpsideGap2Crows, CdlXSideGap3Methods

Supporting changes:
- functions.go: add 25 C function pointer declarations (TA_CDL* signatures)
- loader.go: register all 25 new symbols via purego.RegisterLibFunc in Load()
- cli/main.go: extend smoke harness to exercise all new wrappers
- README.md: document all new patterns in the Pattern Recognition section
