feat(normalized): Phase 141 P1.5 - external env inputs + KnownIntrinsic SSOT
## Task B: External env input bug fix (Priority 1)
Fix: Suffix normalization couldn't access prefix-built local variables
**Problem**: `s.length()` failed because 's' (from prefix `s = "abc"`) was
not in available_inputs during suffix normalization.
**Root cause**: `AvailableInputsCollectorBox::collect()` only collected
function params and CapturedEnv, missing `builder.variable_map`.
**Solution**: Add `prefix_variables` parameter with 3-source merge:
1. Function params (highest priority)
2. Prefix variables (medium priority - NEW)
3. CapturedEnv (lowest priority)
**Changed files**:
- src/mir/control_tree/normalized_shadow/available_inputs_collector.rs
- src/mir/builder/control_flow/normalization/execute_box.rs
- src/mir/builder/control_flow/joinir/patterns/policies/normalized_shadow_suffix_router_box.rs
- src/mir/builder/control_flow/joinir/routing.rs
- src/mir/builder/stmts.rs
- src/mir/control_tree/normalized_shadow/dev_pipeline.rs
- docs/development/current/main/design/normalized-expr-lowering.md (Available Inputs SSOT section)
**Tests**: 3 new unit tests (prefix merge, priority order)
## Task A: KnownIntrinsic SSOT化 (Priority 2)
Eliminate string literal scattered matching by centralizing to registry.
**Problem**: Adding new intrinsics required editing if/match chains with
hard-coded string literals (`if method == KnownIntrinsic::Length0.method_name()`).
**Solution**: Create `KnownIntrinsicRegistryBox` as SSOT:
- `lookup(method, arity) -> Option<KnownIntrinsic>`
- `get_spec(intrinsic) -> KnownIntrinsicSpec`
- Adding new intrinsics now requires: (1) enum variant, (2) registry entry only
**Changed files**:
- src/mir/control_tree/normalized_shadow/common/known_intrinsics.rs (NEW)
- src/mir/control_tree/normalized_shadow/common/expr_lowerer_box.rs
- src/mir/control_tree/normalized_shadow/common/expr_lowering_contract.rs (deprecated methods removed)
- src/mir/control_tree/normalized_shadow/common/mod.rs
- docs/development/current/main/design/normalized-expr-lowering.md (Known Intrinsic SSOT section)
**Impact**: ~30% code reduction in intrinsic matching logic
## Task C: Better diagnostics (Priority 3)
Add `OutOfScopeReason::IntrinsicNotWhitelisted` for precise diagnostics.
**Changed files**:
- src/mir/control_tree/normalized_shadow/common/expr_lowering_contract.rs (enum variant)
- src/mir/control_tree/normalized_shadow/common/expr_lowerer_box.rs (diagnostic logic)
