v0.8.25

Summary

• Heartbeat / org_spec: default prompt gates HEARTBEAT_OK on pool_org(read) and explicit org_spec convergence (no hardcoded phase rules in Rust).
• Supervisor attention: quiet boards after early milestones no longer suppress periodic heartbeat when global coordination is still required.

Verification

• cargo fmt, cargo clippy -D warnings, cargo test (pisci-core / pisci-kernel / pisci-cli) on Linux.
