fix(lean): reduce E4_sq_eq_E8_coeff to single modular-form q-expansion gap
...
Fully prove the E4^2=E8 Fourier coefficient identity (E4_sq_eq_E8_coeff) modulo one isolated, honestly-named Mathlib gap.
- Add E4_sq_eq_E8_qExpansion: the lone irreducible step (E4^2=E8 as q-expansions). Blocked on dim M8(SL2Z)=1 / valence formula, absent in Mathlib v4.30 (LevelOne.lean proves Module.rank only for weight <= 0).
- Machine-check the entire coefficient extraction for E4_sq_eq_E8_coeff: E4 coeff = 240*sigma3, E8 coeff = 480*sigma7, constant term 1, antidiagonal coeff_mul split into 480*sigma3 boundary + 240^2*convolutionLHS middle, then exact_mod_cast C->N. Previously a single hand-waved sorry.
- Wrap in section ModularFormReduction with local opens (ModularForm EisensteinSeries ModularFormClass) to avoid name clashes.
- Update AGENTS.md + .cursorrules: E8Sidon sorry inventory 6 -> 4.
E8Sidon sorries now: E4_sq_eq_E8_qExpansion (Mathlib-blocked), collision_excess_decrease, greedy_sidon_extraction, e8_singer_improvement.

feat(lean): close sidon_iff_zero_collision (both dirs) and erdos30_e8_conditional
...
Close 3 sorry tokens (forward, backward, erdos30):
- sidon_iff_zero_collision forward: double-inclusion proves filter = same∪swap,
inclusion-exclusion gives card = (2k-1)k exactly.
- sidon_iff_zero_collision backward: cardinality squeeze shows filter = same∪swap
when excess=0, then classify each element via same/swap membership.
- erdos30_e8_conditional: difference injection into Icc 1 N + trichotomy
partition gives k(k-1) ≤ 2N, contraposition via nlinarith closes the bound.
E8Sidon sorry count: 9 → 6 (across 6 theorems).
All remaining sorries documented with TODO(lean-port).

chore: rename workspace from nodupelabs to researchstack
...
Updated workspace name in all ContextStream configuration files to match
the actual project name. Workspace ID and project name remain unchanged.
