Logs the 4-commit step-3 batch (69dcee8 → 8b457ff):
- 3a.A/3a.B: parser + AST + resolver for `$args[$i]` in type
positions (return, param, local-var annotation).
- 3a.C: extend resolution to fn-pointer type literals — the
shape step 5's generic Into(Block) trampoline body needs.
- 3b: `type_eq` + `has_impl` comptime intrinsics (`type_name`
already existed). Both fold via `tryConstBoolCondition` so
`inline if type_eq/has_impl` collapses at lower time.
Step 5 (generic Into(Block) impl) is now type-system-unblocked.
Step 4 (#insert pack passthrough + compile_error) is the
smaller intermediate slice if needed before pushing into the
stdlib refactor.
Issue 0047 (`#run` stderr vs runtime stdout split) noted in
"Current state" — filed but not blocking.
Test count: 208/208.
