Phase 5/6 complete: Transients, meta/with-meta, instance?
T5.5 Transients (transient/persistent!/conj!/assoc!) - Mutable builder for batch vector/map operations - Use with let bindings for proper ordering T6.10 meta/with-meta — metadata on any CljVal via ref object field T6.11 instance? — type predicate (instance? :integer 42) Also marked T9.1 Atoms as done (already implemented earlier) 86 tests pass, all examples work. Phases 0-6 now complete. Phase 7: 2/4 tasks done.

**Why HAMT matters**: Current Vector is a Nim `seq` — every `conj` copies the entire array (O(n)). Real Clojure uses Hash Array Mapped Trie for O(log₃₂ n) updates with structural sharing.
