nyash-codex dda65b94b7 Phase 21.7 normalization: optimization pre-work + bench harness expansion

- Add opt-in optimizations (defaults OFF)
  - Ret purity verifier: NYASH_VERIFY_RET_PURITY=1
  - strlen FAST enhancement for const handles
  - FAST_INT gate for same-BB SSA optimization
  - length cache for string literals in llvmlite
- Expand bench harness (tools/perf/microbench.sh)
  - Add branch/call/stringchain/arraymap/chip8/kilo cases
  - Auto-calculate ratio vs C reference
  - Document in benchmarks/README.md
- Compiler health improvements
  - Unify PHI insertion to insert_phi_at_head()
  - Add NYASH_LLVM_SKIP_BUILD=1 for build reuse
- Runtime & safety enhancements
  - Clarify Rust/Hako ownership boundaries
  - Strengthen receiver localization (LocalSSA/pin/after-PHIs)
  - Stop excessive PluginInvoke→BoxCall rewrites
- Update CURRENT_TASK.md, docs, and canaries

MIR Builder — Calls SSOT

Scope

This directory is the single source of truth for call shaping in the builder.
Responsibilities: target resolution, extern mapping, method lookup, flags/effects, MIR emission.

Out of scope

Runtime dispatch details (VM/LLVM) and legacy by-name resolution. The VM keeps a legacy resolver only behind a dev flag for bring-up.

Contract

Builder must populate MirInstruction::Call with a concrete Callee whenever possible.
Arity and canonical names are normalized here so runtimes can be simple routers.

Phase-3 alignment

VM call resolver is treated as legacy-only. Default runtime disables by-name fallback.
Extern interface normalization aligns with handlers/calls/externs.rs (runtime SSOT for extern dispatch).
