Add real FreeBSD 15 read-only validation output and the hardening findings so Linux-side reviewers can evaluate the installer follow-up without needing host access.\n\nChecks: ./scripts/check-format.sh; git diff --check
Use the clawdie service user in the generated FreeBSD rc.d script, chown state directories after the user is created, and reject unknown existing ZFS pools before rendering/applying a plan. Update the FreeBSD validation handoff to cover these checks.\n\nFreeBSD checks: cargo fmt --check; ./scripts/check-format.sh; git diff --check; cargo test -p clawdie -- --nocapture; cargo clippy -p clawdie --all-targets -- -D warnings; cargo build -p clawdie --release; target/release/clawdie discover; target/release/clawdie plan; target/release/clawdie apply --pool zroot (dry-run); target/release/clawdie plan --pool does-not-exist (expected error).
