audit: classify 2 PA021 legitimate mathematical axioms (funext + Conflicts)#107

Conversation
Two Agda postulates flagged by PA021, both with inline justification:
proofs/agda/Basic.agda: funext (function extensionality) — HoTT-standard
axiom; Coq's FunctionalExtensionality, Lean's funext, HoTT Axiom 2.9.3.
Provable in Cubical Agda; postulated in plain Agda.
proofs/agda/SoundnessPreservation.agda: Conflicts is an INTENTIONAL
parameter (abstract binary predicate); the caller supplies a concrete
proof of ¬ Conflicts at use-site. Theorem interface, not debt.
Adds:
- audits/assail-classifications.a2ml (entries=2)
- audits/audit-pa021-axioms-2026-05-26.md
Anti-gameability: only these two postulates suppressed; new postulates in
these or other proof files remain visible.
Refs hyperpolymath/panic-attack#32 (estate sweep tracker).

Previous commit on this branch overwrote the existing 14 FFI-boundary classification entries in audits/assail-classifications.a2ml. This commit restores them in full and re-appends the 2 new PA021 entries. No-op semantically vs the intended PR state, but corrects the diff.
