Complete FSPE table with Streptolysin O; portablize SLURM conda path

FSPE headline table (README, HF card, system card) omitted Streptolysin O,
a residue of the 2026-05-20 accession correction: it carried the non-existent
P0C0I2 until re-keyed to P0DF97, after which the pipeline produced a valid,
nominally significant FSPE (0.509, p=0.025, r=+0.58) that was never added to
the displayed table. The curated summary_risk_table.csv preview included it,
surfacing the gap. Added the row and updated "mean 0.66, 5/7 below 1.0" to
"mean 0.64, 6/8 below 1.0" in all three docs; logged in DATA_CORRECTIONS.md.
Pooled meta-analysis (74/300, p=2.6e-8) is unchanged. FSPE panel (8) and FSI
panel (7, SEB excluded) legitimately differ.

SLURM scripts hardcoded a personal double-path conda location
(~/miniconda3/miniconda3/...) that breaks for anyone cloning. Replaced across
19 scripts with ${CONDA_SETUP:-$HOME/miniconda3/etc/profile.d/conda.sh} and
documented CONDA_SETUP in ARCHITECTURE.md.

+## 2026-06-04 — FSPE headline table completed with Streptolysin O
+
+### Summary
+
+The headline FSPE table (README, Hugging Face card, system card §5) listed
+**7 proteins** and omitted Streptolysin O. This was a residue of the
+2026-05-20 accession correction: Streptolysin O originally carried the
+non-existent accession `P0C0I2`, so it had no ESM-2 FSPE value when the table
+was first built. After re-keying to the reviewed accession `P0DF97`, the FSPE
+pipeline produced a valid, nominally significant result for it
+(`fspe_ratio = 0.509`, Mann–Whitney `p = 0.025`, `r = +0.58`, expected
+direction), present in `results/fspe_results.json` but never added to the
+displayed table. The `results/summary_risk_table.csv` preview (the 8-toxin
+panel) did include it, surfacing the gap.
+
+### Fix
+
+- Added the Streptolysin O (`P0DF97`) row to the FSPE table in `README.md`,
+  `huggingface/README.md`, and `docs/SYSTEM_CARD.md`.
+- Updated the descriptive statistic from "mean 0.66, 5/7 below 1.0" to
+  **"mean 0.64, 6/8 below 1.0"** in all three documents.
+- The pooled meta-analysis (74 functional vs 300 background residues,
+  `p = 2.6 × 10⁻⁸`, `r = 0.41`) is unchanged — it was already computed over
+  the full residue set and did not depend on which rows the table displayed.
+
+### Impact
+
+No metric value changed; one already-computed result that had been omitted
+from the headline table is now shown. The displayed FSPE panel (8 proteins)
+and the curated `summary_risk_table.csv` preview are now consistent. The FSI
+panel remains 7 scored structures (SEB excluded as a superantigen), so FSPE
+(8) and FSI (7) panel sizes legitimately differ.

 - **Negative controls constrain interpretation.** Astacin (FSI 1.85) and thermolysin (FSI 1.69) — mechanism-matched *benign* zinc proteins — show elevated FSI comparable to BoNT-A. FSI alone cannot distinguish dangerous zinc-protease from benign zinc-protease.
 - **Panel size.** Seven FSI-scored toxins across four mechanism families. Extrapolation beyond this panel is not warranted.

The remaining proteins contribute a more modest left-shift relative to background.
