Quick Win 1: Show available boxes on "Unknown Box type" error
- vm.rs, vm_fallback.rs: Display sorted list of available user-defined boxes
- Before: "Unknown Box type: Foo"
- After: "Unknown Box type: Foo. Available: Bar, Baz, Main"
Quick Win 2: Show stderr on child process timeout
- child.rs, selfhost_exe.rs: Capture and display stderr (up to 500 chars)
- Helps diagnose what went wrong in selfhost compiler child process
Quick Win 3: Simplify Stage-B compiler API (SSOT)
- compiler_stageb.hako: Add StageBDriverBox.compile() as single entry point
- compiler_stageb.hako: Remove StageBMain compatibility wrapper
- compiler.hako: Change from `using ... as StageBMain` to direct import
- compiler.hako: Call StageBDriverBox.compile() directly
Also includes child_env.rs NYASH_MODULES env var for module mapping.

- Use --stage-b flag for file-based compilation (Stage-A expects source
content, not path; Stage-B uses FileBox to read files)
- Remove redundant env overrides that conflicted with
apply_selfhost_compiler_env() settings
- Re-enable plugins in selfhost compiler env (NYASH_DISABLE_PLUGINS=0)
so compiler.hako can use FileBox to read source files
Note: Pipeline infrastructure now works, but compiler.hako has a MIR
SSA bug (undefined ValueId(374)) that needs separate investigation.

Phase 25.1b: Complete SSA fix - eliminate all global ValueId usage in function contexts.
Root cause: ~75 locations throughout MIR builder were using global value
generator (self.value_gen.next()) instead of function-local allocator
(f.next_value_id()), causing SSA verification failures and runtime
"use of undefined value" errors.
Solution:
- Added next_value_id() helper that automatically chooses correct allocator
- Fixed 19 files with ~75 occurrences of ValueId allocation
- All function-context allocations now use function-local IDs
Files modified:
- src/mir/builder/utils.rs: Added next_value_id() helper, fixed 8 locations
- src/mir/builder/builder_calls.rs: 17 fixes
- src/mir/builder/ops.rs: 8 fixes
- src/mir/builder/stmts.rs: 7 fixes
- src/mir/builder/emission/constant.rs: 6 fixes
- src/mir/builder/rewrite/*.rs: 10 fixes
- + 13 other files
Verification:
- cargo build --release: SUCCESS
- Simple tests with NYASH_VM_VERIFY_MIR=1: Zero undefined errors
- Multi-parameter static methods: All working
Known remaining: ValueId(22) in Stage-B (separate issue to investigate)
