Outputs are stored under `historical/<PROGRAM>/<SLOT>.so`. If a slot file already exists, it will be skipped.

### Extract historical IDL versions:

Reconstruct and store historical Anchor IDL versions for a program:

```bash
./target/release/gg-program-resurrect idl-history --program 6EF8rrecthR5Dkzon8Nwu78hRvfCKubJ14M5uBEwF6P --output ./idl-versions
```

The command:
- Derives the Anchor IDL account address using the canonical `anchor:idl` seed pattern
- Detects IDL versions through Create and SetBuffer instructions
- Reconstructs IDL content from Write instruction sequences
- Handles zlib-compressed IDL data
- Saves each version as `{slot}.json` in the output directory
