Extend CapturedEnv to include function parameters used in loop conditions,
enabling ExprLowerer to resolve variables like `s` in `loop(p < s.length())`.
Phase 245C changes:
- function_scope_capture.rs: Add collect_names_in_loop_parts() helper
- function_scope_capture.rs: Extend analyze_captured_vars_v2() with param capture logic
- function_scope_capture.rs: Add 4 new comprehensive tests
Test fix:
- expr_lowerer/ast_support.rs: Accept all MethodCall nodes for syntax support
(validation happens during lowering in MethodCallLowerer)
Problem solved: "Variable not found: s" errors in loop conditions
Test results: 924/924 PASS (+13 from baseline 911)

Migrated Pattern 1 (Simple While) to use JoinValueSpace for unified
ValueId allocation, following the same pattern as Pattern 2 (Phase 201).
Changes:
- simple_while_minimal.rs: Added join_value_space parameter, replaced
value_counter with join_value_space.alloc_local()
- pattern1_minimal.rs: Create JoinValueSpace before calling lowerer
- loop_view_builder.rs: Create JoinValueSpace in try_pattern1()
Pattern 1 uses Local region (1000+) only, since it doesn't need
ConditionEnv (no Param region allocation required).
Tested:
- cargo build --release --lib: Success (0 errors, 4 warnings)
- cargo test --release --lib pattern: 119 passed
- E2E test apps/tests/loop_min_while.hako: Outputs "0 1 2" correctly
