nothrow @trusted @nogc

Core greedy compression loop operating entirely on raw pointers.

Uses a malloc-allocated hash table (passed as a raw uint*) to keep the hot loop completely free of GC involvement — no safepoint polls, no bounds checking, no GC scanning of the table.

Parameters

`srcPtr`	Pointer to input data.
`srcLen`	Length of input data in bytes.
`outPtr`	Pointer to pre-allocated output buffer.
`maxOut`	Capacity of the output buffer.
`hashTblPtr`	Raw pointer to malloc'd hash table (filled with 0xFFFF_FFFF).
`hashBits`	Number of hash bits (log2 of table size).

Returns

Number of bytes written to outPtr.
