docs: prune research vault to theory-only scope

Browse Source 
Remove gA-extraction notes, nuclear-structure notes, paper-summary
refs, detector-response correction note and the finished test
migration checklist. Rewrite the vault index for the single-package
theory calculator; repoint dangling wiki-links in surviving notes to
inline citations; refresh docs_check.py (drop bs_exp CLI check,
register removed files).

Literature and nuclear-structure research resumes in dedicated
projects; the removed notes are recoverable from history.

## Precision Goal
The Hayen paper achieves **accurate to a few parts in $10^{-4}$ down to 1 keV** for low-to-medium $Z$ nuclei — extending previous work by nearly an order of magnitude [[refs/electromagnetic/2017_Hayen_analytical_beta_shape/summary]].

> [!key] Why this matters
> A precision of ~0.5% is required when determining the Fierz term $b_{\text{Fierz}}$ to improve limits on BSM scalar/tensor couplings. Weak magnetism $b_{wm}$ must be included as experimental precision increases, otherwise it limits BSM sensitivity.
