feat: add TBF (Ehlers Truncated BandPass Filter) + fix all 64 warnings
TBF indicator:
- Sealed class with RingBuffer, stackalloc scratch, O(Length) per bar
- 7 core files: Tbf.cs, Tbf.Quantower.cs, Tbf.md, tbf.pine, 3 test files
- 67 tests (48 lib + 19 Quantower) all passing
- Full integration: sidebar, indexes, docs, Python bridge, exports
AMFM fix:
- Added envBuf.Clear()/smaBuf.Clear() after stackalloc in Batch
(SkipLocalsInit garbage values caused 8.97e+65 blowup)
Warning fixes (64 → 0):
- Amfm.cs: S125 commented code removed, 11× IDE0011 braces
- Pta.cs: 11× IDE0011 braces on if/else/for/foreach
- Pta.Tests.cs: 14× IDE0011, S1481 unused var, S2699 assertion, 2× MA0074
- Lpf.Quantower.Tests.cs: 2× MA0074 StringComparison
Build: 0 warnings, 0 errors, 20,048 tests passing

feat: add LPF - Ehlers Linear Predictive Filter (TASC Jan 2025)
Implements Ehlers' Linear Predictive Filter for dominant cycle detection:
- Roofing filter (HP + SuperSmoother) → AGC → Griffiths adaptive predictor
- DFT spectrum from predictor coefficients → Center of Gravity dominant cycle
- Outputs: DominantCycle, Signal (AGC-normalized), Predict (one-bar-ahead)
Files added:
- lib/cycles/lpf/Lpf.cs (core implementation, sealed class)
- lib/cycles/lpf/Lpf.Quantower.cs (3 LineSeries: Cycle, Signal, Predict)
- lib/cycles/lpf/Lpf.md (canonical template v3 documentation)
- lib/cycles/lpf/lpf.pine (PineScript v6 reference)
- lib/cycles/lpf/tests/Lpf.Tests.cs (38 unit tests)
- lib/cycles/lpf/tests/Lpf.Quantower.Tests.cs (22 adapter tests)
Updated: index files, Python bridge (Exports.cs, _bridge.py, cycles.py)
