docs(file-ops): add version tracking in checksum registry

Follow project pattern for tool version management by adding
file-ops-component to the centralized checksum registry.

Changes:
- Add checksums/tools/file-ops-component.json with version history
- Document v0.1.0-rc.2 (current, stable, 853KB)
- Document v0.1.0-rc.3 (latest, AOT support, pending CI assets)
- Update MODULE.bazel comments to reference checksum registry
- Note rc.3 performance improvements: 100x faster startup, 2-5x runtime

This follows the existing pattern used by wasm-tools, wasmtime, wizer, etc.
for consistent version and checksum management across all external tools.
