Update manifest and github yaml

In order to reduce the diff in the previous patch, the actual changes
generated by the generate-files.sh script should be split into a new
patch.

Run fuzz/generate-files.sh.

The short version
What changed, and why it matters

This commit only adds new fuzz testing targets and updates build/CI configuration to run them. It does not change any production library code, so it cannot introduce a runtime security vulnerability in the released crate. It is a testing infrastructure change.
Recommended action
No security action required. Review the fuzz harness helper functions (bitcoin_fuzz::check_roundtrip and check_script_roundtrip) in the accompanying commit if assessing test coverage, but this commit itself is benign infrastructure.
Security signals we found

No strong security signals were identified.
Technical analysis
Evidence from the diff

The commit regenerates fuzz target manifests via fuzz/generate-files.sh. It adds 71 new encoding_roundtrip fuzz targets under fuzz/fuzz_targets/bitcoin/encoding_roundtrip/, registers them in fuzz/Cargo.toml, and lists them in .github/workflows/cron-daily-fuzz.yml. It also adds a [lib] section to fuzz/Cargo.toml. No source code in the bitcoin or p2p crates is modified.
