feat(toolchain): port to FULL Rust — dichotomy wave
Contract BUILDER-2026-10-11T22:03:40Z-7aeb7a-factory-wave (#2479 tranche).
Faithful port of src/rune/toolchain.py: ToolchainConstraints known/unknown
classification, DecisionRecord normalization, _major_change,
resolve_toolchain (INSUFFICIENT_EVIDENCE gate, KEEP_EXISTING,
CHANGE_MAJOR, greenfield recommendation), CONSTRAINT_KEYS vocabulary.
Doc-envelope FFI (tl_* symbols, free via cs_free_string), ctypes loader
(tl_loader.py, TC_RUST_LIB override), facade delegation with
RUNE_TC_CORE=python pin. Frozen oracle truth: 43 cases across every
public function and branch (frozen_tc_truth.json), replayed VERBATIM by
branch_battery.rs (6 tests). Live parity 613/613 (truth + 570 fuzz,
seed 2479).
