v0.1.0 — substrate complete

First public release. Three primitives shipped and validated end-to-end.

What's in v0.1.0

• swarm_lib.claims — atomic-rename queue primitives (enqueue / try_claim / complete) backed by POSIX os.replace. Multiple workers race for tasks; exactly one wins.
• swarm_lib.status — status.json checkpoint state with strict schema versioning, idempotent append_completed, additive-merge write, fresh initialize.
• swarm_lib.cli — swarm-cli console entry point exposing all primitives for shell consumers. jq-friendly single-line JSON output.
• swarm_lib/worker_loop.sh — generic consumer loop that ties everything together. Polls a queue, claims atomically, invokes a user-supplied handler, marks done/failed.
• examples/seven-step-chain/ — Tribunal-shaped reference consumer (driver + self-chaining handler) demonstrating the substrate against a real-world multi-step workflow.

What's validated

48 total smoke checks pass across the substrate:

• 14 unit-level (claims + status + claims↔status integration)
• 13 CLI + worker_loop end-to-end
• 21 seven-step chain (full Tribunal-shaped workflow runs to completion)
