feat(authority): add authority behavior, logratio+SI metrics, prune dead code

- Add AUTHORITY_PROMPT + 3 persona pairs (MFT-paper framing, sl-identical)
- Wire authority into data._personas/_topics/_build_specs
- Add SINGLE_FOUNDATION + _axis_shift for single-foundation behaviors
- Add logratio to per-vignette/frame scoring (same convention as sl)
- Add _si.py: port si_per_foundation from sl foundations.py
- Drop prompt_baseline mode, repe, sycophancy, subspace, run_demo
- Strip kl_calibrate to dW-only; remove repe+prompt_texts deps
- Simplify replicate.py to train+diff only (no eval/demo/subspace)
- Default behavior="authority" across eval, sweep, replicate
- Install tinymfv git dep; flash_attn 2.6.3 prebuilt wheel

-"""Subspace alignment for the diff vector w.
-
-We test whether the steering direction `w_layer = θ+_layer - θ-_layer` lies
-preferentially in interpretable subspaces of the pretrained model, rather
-than in random directions.
-
-Two weight-only tests (no activations needed):
-
-1. SVD-of-W (per layer)
-   For W = U @ diag(S) @ V^T, project w into the SVD basis:
-       proj = U^T @ w @ V       # shape (r, r)
-   Energy in the top-k×k block / total energy.
-   Null (uniform random matrix): (k/r)² because a random direction has
-   equal energy in any orthonormal pair of k-dim subspaces of size k×k.
-   ratio > 1 ⇒ w concentrates in W's principal components (PiSSA-aligned).
-
-2. Weak-readout (for params whose output is the residual stream: o_proj, down_proj)
-   SVD of lm_head: lm_head = U_lm @ diag(S_lm) @ V_lm^T, V_lm rows live in residual space.
-   Bottom-frac rows of V_lm = "weak-readout" directions (logits read them weakly).
-   Energy of w's row-space (output side) in those directions / total ||w||².
-   Null = frac.
-   ratio > 1 ⇒ w writes into directions the unembedding ignores.
-
-Two activation-based subspaces (Suppressed, Stenographic) are deferred:
-they need a probe set of forward passes through the base model.
-
-Returns polars DataFrames so we can group by param-kind (q_proj / o_proj / ...)
-and see which families of weights carry the steering signal.
