Constant PEFT_SUPPORTED_TARGET_MODULES 

pub const PEFT_SUPPORTED_TARGET_MODULES: &[&str];

v0 target-module allow-list. Deltas apply on full-attention layers (holo-3.1-0.8b: layer indices 3,7,11,15,19,23) plus the dense SwiGLU FFN. q_proj IS supported: on attn_output_gate=true models the raw projection emits the interleaved [Q|gate] at width 2·q_heads·head_dim — the FULL width the PEFT lora_B was trained against (verified [8192,16] on holo-3.1-35b), so the delta folds onto the raw interleaved basis exactly like k/v/o (the deinterleave is deferred past the fold). GDN/linear-attention modules stay rejected (no exact-replay parity harness for the recurrence yet).
