863da04f21 feat(avm-ports): port AVM ISA to all 12 scientific languages
Lean (reference), Python, Rust, C, C++, Go, Julia, R, Scala, Fortran,
Coq, Octave — all implementing the same AVM ISA v1 specification.

Every port implements:
- Full type universe: Q0_16, Q16_16, Bool
- 11 primitives with floor division (Lean Int.ediv), V6 signed comparison,
  symmetric clamping [-2147483647, 2147483647]
- 12 instruction opcodes with stack depth limit (1024)
- Fuel-bounded run loop
- Error handling (stack under/overflow, type mismatch, div-by-zero, jump OOB)

1ae311c63f fix(avm-ports): add Q0_16 support to Julia and R ports
Julia port:
- Extended type tracking from Bool (is_q16) to Int8 tri-state (TYPE_BOOL/Q16/Q0)
- Added ADD_SAT_Q0 / SUB_SAT_Q0 primitive handling
- Added avm_q0_clamp for symmetric Q0_16 range [-32767, 32767]

R port:
- Added PRIM_ADD_Q0 / PRIM_SUB_Q0 primitives
- Added push_q0 instruction, make_q0 / is_q0 helpers
- Added avm_q0_clamp for symmetric Q0_16 range
- Fixed LOAD to preserve type tag on restore

All three ports now support the full AVM ISA type universe (Q0_16, Q16_16, Bool).

aeb87d86c8 fix(avm-ports): align all 3 ports with Lean reference
Fixes applied to Rust, Julia, and R AVM ISA ports:

1. Division rounding: use floor division (matching Lean Int.ediv)
2. Clamp range: symmetric [-2147483647, 2147483647] for Q16_16,
   [-32767, 32767] for Q0_16 (preserves negation involution)
3. V6 sign-decomposition comparison for ltQ16
4. Stack depth limit: maxStackDepth = 1024 with StackOverflow error
5. Added AVM-specific constants and helpers to each port

All three ports now match the Lean reference specification.
