Per-module ISO 26262 MC/DC campaign (iso26262-mcdc-per-module). Adds DecisionCoverage-style cases to tests/api/test_chacha.c and test_poly1305.c, plus intel-dispatch white-box supplements mirroring the aes/sha3 technique. chacha.c: BEFORE 6/11 (54.55%) -> AFTER 13/13 (100%). Closed wc_Chacha_SetIV/SetKey's NULL-argument independence pairs, wc_Chacha_Process's input/output NULL-argument pairs (both the portable-C and USE_INTEL_CHACHA_SPEEDUP physical copies), and the (msglen>0 && ctx->left>0) leftover-block decision's msglen==0 side. Also adds an unaligned-key SetKey case (XSTREAM_ALIGN), a half-length key case, and a new test_wc_Chacha_XChachaSetKey covering wc_XChacha_SetKey. Total rose from 11 to 13 once the intelasm variant was fixed (see campaign notes): it carries its own physical copy of the leftover decision that the portable-only union previously missed. poly1305.c: BEFORE 10/14 (71.43%) -> AFTER 12/14 (85.71%). Closed wc_Poly1305Update's (m==NULL && bytes>0) inner AND, both operands. Also adds an addSz==0 case to wc_Poly1305_MAC and a lenToPad==WC_POLY1305_PAD_SZ case to wc_Poly1305_Pad for API robustness. The 2 remaining conditions are structural/dead-code residuals: wc_Poly1305SetKey's compound key==NULL check is shadowed by an earlier unconditional key==NULL guard a few lines above (dead code); wc_Poly1305_Pad's paddingLen<WC_POLY1305_PAD_SZ operand is always true whenever paddingLen>0 (paddingLen is a mod-16 value bounded to 0..15). See campaign baselines.json for full detail.
