- Add output/* to .gitignore (negated .gitkeep)

(parameters now come from ENSDF data or custom JSON input)
- Clarify energy units in all CLI help text (MeV throughout, keV for detector params)
- Enhance logging verbosity:
- -v (INFO): shows source, component initialization, workflow steps
- -vv (DEBUG): shows detailed internals of all spectrum components
(parameters, evaluation counts, input/output ranges)
- Improve CSV headers with element notation (e.g. Tc99 -> Ru99)
- Add CONVENTIONS.md documenting energy unit and logging conventions
- Update TODO.md with completion status
- TODO.md: cross out completed A2 (detector response) and A4 (fitter/CW extraction) items with strikethrough and implementation notes
- README.md: replace redundant Components and Additional Modules tables with Implementation Status section referencing TODO.md
- Eliminates duplicate status tracking between README and TODO
- Remove empty beta_spectrum/components/recoil.py (0-line stub)

Corrections' deferred item, update Current Status to 0.3.0 with actual
implementation list, mark A4 as complete, set A3 as next step

Bump version to 0.3.0.
- CONVENTIONS.md: natural units (m_e=hbar=c=1), W vs MeV energy representation,
conversion helpers, SpectrumComponent interface, physics-specific testing
- DEVELOPMENT.md: removed physics-specific 'What to Test' section,
references CONVENTIONS.md for physics testing guidelines
The resummation was previously applied to all energy points when the
flag was set, causing resummed and standard modes to differ everywhere.
Per spec, it should only replace C(beta)*ln(W0-W) with the resummed
power-law form when (W0-W) < delta_cut (~1e-3).
Adds delta_cut parameter (default 1e-3) and corrects the resummation
switch test to verify identical results far from endpoint.
- Add Z (nuclear charge) and A (mass number) parameters to RadiativeCorrection
- Implement O(Z*alpha^2) finite nuclear size correction per Sirlin 1987:
