Brandon Schneider 5bd23d274b chore(lean): stub 6 Q16_16 arithmetic lemmas with TODO(lean-port) 
FixedPoint.lean: add stubs for abs_triangle, sub_eq_add_neg,
mul_mono_left/right, add_le_add, abs_nonneg, abs_mul_le.
All blocked by the same core issue: calc/rw/omega fail on
ofRawInt-projected Int arithmetic after unfold mul/add/abs/neg.
The pattern that works in PistSimulation (unfold + Int.ediv_le_ediv
+ ofRawInt_toInt_eq_clamp + q16Clamp_monotone) fails here
because the goal structures differ.

Known-working pattern to finalize:
  1. unfold the Q16_16 op
  2. have h2 := raw Int inequality (Int.mul_le_mul_of_nonneg_*)
  3. have hdiv := Int.ediv_le_ediv (by norm_num) h2
  4. rw [ofRawInt_toInt_eq_clamp, ofRawInt_toInt_eq_clamp]
  5. exact q16Clamp_monotone _ _ hdiv

AGENTS.md: document 6 new TODO(lean-port) items in Pending Proof Work.
