Crate taskfleet_core 

Core library for taskfleet.

See issues/taskfleet-mvp/design.md for the canonical schema and protocol references. This crate provides:

• The on-disk schema types (Manifest, Node, Event).
• Atomic write helpers (atomic) and per-run advisory flock (RunLock).
• The canonical mutation entry point (append_and_apply_event): append one event and fold it into the projections under the run’s flock.

Higher-level supervisor and CLI logic live in their own crates / issues.

taskfleet-core is the canonical library surface, so public items are required to carry doc comments (#![warn(missing_docs)]). Lint-level policy otherwise lives in the workspace [workspace.lints] table (pedantic clippy).
