unzhakov 272841f50d feat: add χ² fitter and C(W) shape factor extraction modules 
Add CurveFitter with scipy least_squares, configurable loss functions
(soft_l1, huber, cauchy), profile likelihood, confidence intervals, and
goodness-of-fit metrics. Add CWExtractor for extracting shape factors
from beta spectra via Kurie analysis, parametrization fitting, and
g_V/g_A extraction. Includes 32 new tests (18 fitter + 14 CW extractor).
Bump version to 0.3.0.

unzhakov 5f99566a0e feat(detector): add detector response module, convolution, and integration 
- Analytical detector response: gaussian, gaussian_tail, tikhonov models
- Low-energy tail modeling for charge collection effects
- Response matrix convolution via R^T · (Φ·ΔW)
- Declarative API: create_detector_from_config(), convolve_detector()
- BetaSpectrumAnalyzer.convolved_spectrum() for auto-convolution
- Integration tests: TestBetaSpectrumIntegration, TestDeclarativeDetectorResponse
- Documentation: docs/08-detector-response.md
