Summary

Merges PR #11 (multi-worker parallelism + early-exit optimization) on top of PR #8 (Windows/Node FNV-1a fix), adopting the 8-core cap from PR #10.

• Multi-worker parallelism: Spawns up to 8 workers (one per core, capped at 8) for ~Nx wall-clock speedup
• Early-exit in hot loop: Inlined quickRoll() with per-attribute checks — mismatches skip remaining RNG calls immediately
• FNV-1a support preserved: Workers use hashKey() abstraction that dispatches to FNV-1a or Bun.hash based on --fnv1a flag
• Progress display: Shows [N cores] during search and total attempts across all workers
• Reduced IPC overhead: Progress reporting interval bumped from 25K to 100K iterations

Credits:

• @Co-Messi for PR perf: multi-worker parallelism + early-exit in brute-force #11 (multi-worker + early-exit)
• @joshpocock for PR fix: use FNV-1a hash for Node-based Claude installs (Windows npm) #8 (FNV-1a Windows fix, already merged)
• @Ahmad8864 for PR Feat/multi-core-parallel-salt-finding #10 (8-core cap idea)

Closes #11

Test plan

• node --check passes on all modified files
• CLI launches and runs correctly (smoke tested interactive flow)
• Verify multi-core progress display ([N cores])
• Verify search completes and correctly patches the binary
• Test on Node 18.x to confirm no import errors
