feat(quickadapter): replace pi_extensions take-profit series with equal-division and Gann octaves

- Add `equal_division` (k/(n+1)) and `gann_octaves` (Gann octave/third levels closest to the full move, capped at nine) series; remove `pi_extensions` (near-entry bias, no trading basis).
- Rename `fibonacci_extensions` -> `fibonacci_retracements` (fractions are all < 1 = retracements, not extensions > 1); not backward compatible.
- Dispatch the series by `TAKE_PROFIT_STAGE_NATR_MULTIPLIER_FRACTION_SERIES[i]` index through a typed table (project enum-tuple convention).
- Bump version 3.13.2 -> 3.13.3.
