[doesburg11]

Summary

• Add a README link to the PredPreyGrassLegacy archive
• Update the quick start to use the random policy instead of a removed pretrained checkpoint
• Ignore local Conda envs and generated RLlib training outputs
• Remove tracked checkpoints, TensorBoard events, result files, and experiment run artifacts from the active source tree

Verification

• python -m compileall -q src/predpreygrass
• Strict generated-artifact git ls-files check returns no matches

Notes

This removes generated artifacts from the current branch, but it does not rewrite Git history. Historical files remain available in PredPreyGrassLegacy.
