Describe the feature you would like

https://github.com/foundry-rs/foundry/issues/991 was closed by https://github.com/foundry-rs/foundry/pull/1658, but as documented by this comment there's some other related work, so pulling that into separate issues.

---

Follows https://github.com/foundry-rs/foundry/issues/2551 to allow saving and replaying entire fuzz campaigns instead of just failures.

• Capture fuzz campaigns via ResultCache (Or some other mechanism TBD).
• Persist fuzz campaigns to /cache/fuzz/corpus-latest.json.
• Re-use foundry.toml flag to specify outdir.
• Add a replay proptest strategy that is powered by a corpus.json file.
• Extend --fuzz-input-file option to additionally take a corpus.json file & forge test to trigger replay.
• Ensure /cache/fuzz is removed with forge clean.
• Consider a --generate-test-cases flag to autogenerate concrete tests from the fuzz inputs. these can be logged to the console for the user to put anywhere, or inserted directly below the failed fuzz test in the test file

Including the generated dictionary (perhaps as an optional flag if it's too big?) would be useful as well
