Fuzz testing for IronClaw code paths that depend on the full crate, using cargo-fuzz (libFuzzer).

Note: Safety-specific fuzz targets (sanitizer, validator, leak detector, credential detect) have moved to crates/ironclaw_safety/fuzz/. See that directory's README for details.

cargo install cargo-fuzz
rustup install nightly

# Run a specific target (runs until stopped or crash found)
cargo +nightly fuzz run fuzz_tool_params

# Run with a time limit (5 minutes)
cargo +nightly fuzz run fuzz_tool_params -- -max_total_time=300

1. Create fuzz/fuzz_targets/fuzz_<name>.rs following the existing pattern
2. Add a [[bin]] entry in fuzz/Cargo.toml
3. Create fuzz/corpus/fuzz_<name>/ for seed inputs
4. Exercise real IronClaw code paths, not just generic serde

For safety-only targets, add them to crates/ironclaw_safety/fuzz/ instead.
