Brandon Schneider 7a20002fc2 feat: eigensolid convergence proof + QC flagging tool + full pass/fail review
Resolves the convergence_to_fixed_point failure by proving the correct
eigensolid statement: stepExact stabilizes all value components (N_7,
N_8, N_11) in one application. The original theorem was mathematically
false (iteration counter is free-running).

QC cleanup sweep across Physics/ (20 files):
- 3 remaining LOW items fixed: h00/h01 factoring, rD->rd, rdDr1/rdDr2 x100
- 6 of 7 sorry theorems proved; 1 explicitly FAILED (convergence)
- Unused imports removed, naming violations fixed, #eval witnesses added
- 210 -> 144 issues remaining (all WARNING/INFO, zero ERROR)

New tooling:
- scripts/qc-flag/lean_qc_flagger.py implemements 5-point inspection protocol
- Outputs structured JSON + Markdown pass/fail reports
