Commit Message

perf(cypher): add structural expression fast paths

Replace the rejected operator-cache approach with generic expression
fast paths that avoid heavyweight function dispatch for hot predicate
evaluation. Simple leaves, top-level operators, null predicates, and
string predicates now route through allocation-free structural checks
while preserving CASE, quoted literal, array indexing, slicing, and
unknown dotted-expression fallback semantics.

Also make BuildIndexes finish final index persistence before returning,
so admin import with index building does not race temp directory cleanup
or report success before HNSW artifacts are durable.

Results:
- Hot predicate benchmark: ~69 us/op -> ~2.9 us/op
- Speedup: ~23.6x faster
- Allocations: 62 allocs/op -> 0 allocs/op
- Bytes: 1520 B/op -> 0 B/op
