V108: deep debt resolution — AGPL-3.0-or-later, barracuda CPU delegation, typed capability discovery

License corrected to AGPL-3.0-or-later (SCYBORG Provenance Trio) across 302 source
files, LICENSE, and Cargo.toml. barracuda WelfordState CPU delegation for std_dev and
mean_and_std_dev. Tolerance centralization (tol::ANALYTICAL in tests, named geometry
constants with provenance). Typed capability-based discovery: discover_by_capability,
compute_execute, storage_put/get in biomeos/interaction.rs. Python provenance enrichment
(python_version, numpy_version in 29 benchmark JSONs). validate_band_edge evolved to
Result-based error handling. V108 handoff crafted for toadStool/barraCuda team. Stale
pin references (S96c) updated to S155b across active docs and graphs. V107 handoffs
archived; V108 active. 906 tests, 261 Python checks, 0 clippy, 0 fmt diff.

+#### License Correction
+- AGPL-3.0-only → AGPL-3.0-or-later across all 302 source files, LICENSE, Cargo.toml
+  (SCYBORG Provenance Trio: AGPL-3.0-or-later + ORC + CC-BY-SA 4.0)
+
+#### barraCuda CPU Delegation
+- `std_dev` and `mean_and_std_dev` now delegate to `barracuda::stats::welford::WelfordState`
+  when the `barracuda` feature is enabled (CPU path), with local `welford_population` fallback
+
+#### Tolerance Centralization
+- Test assertions in `tissue_anderson/compartments.rs` use `crate::tol::ANALYTICAL`
+  instead of bare `1e-10` literals
+- `tissue_anderson/geometry.rs` on-site energy magic numbers extracted to named constants
+  with provenance comments
+
+#### Typed Capability-Based Discovery
+- New public functions in `biomeos/interaction.rs`: `discover_by_capability`,
+  `compute_execute`, `storage_put`, `storage_get`
+- Runtime-only capability discovery — no compile-time primal knowledge
+
+#### Python Provenance Enrichment
+- All 29 benchmark JSONs enriched with `python_version` and `numpy_version` in `_provenance`
+
+#### Validation Binary Evolution
+- `validate_band_edge.rs` refactored to Result-based error handling with `BenchResult`
+- Determinism check uses `groundspring::tol::DETERMINISM` instead of `f64::EPSILON`
+
+#### Quality Gates
+- 906 tests pass, 0 clippy warnings (pedantic+nursery), 0 fmt diff
+- License: AGPL-3.0-or-later (SCYBORG trio aligned)
+- `cargo doc -D warnings`: 0 warnings
