Detailed Description

Flat bit-array pool backed by a uint32_t word array.

Packs an arbitrary number of boolean flags into ceil(nBits/32) uint32_t words. Access is by flat bit index; mapping from (row, col) coordinates to index is the caller's responsibility.

Two construction modes:

• Heap-owning: BitPool(nBits) — allocates and frees internally.
• Non-owning: BitPool(words, nBits) — caller supplies the word array.

get() and set() are defined inline here so the compiler can inline the two-instruction bit read/write into the call site.
