agenthand 0.2.0 — Rust build

agenthand 0.2.0 — the Rust build becomes the public submission build.

One static binary per platform, no Python runtime. Same three tools
(identify, cut_out, draw), same receipts, measured parity with the
Python reference build: identical output pixel hash on the frozen
proof run (580,613 opaque pixels checked, 0 changed), identical
billed cost to the micro-dollar, ~540x faster cold start.

Assets

• agenthand-0.2.0-<platform>.mcpb — one-click bundles for
  MCPB-supporting clients.
• agenthand-0.2.0-<platform> — bare binaries for any MCP client
  config. Verify against SHA256SUMS.

Platform notes

• macOS: binaries are unsigned and not notarized. Gatekeeper
  blocks the first launch of a browser-downloaded copy; right-click
  → Open, or xattr -d com.apple.quarantine <file>. Notarization is
  a planned, paid step.
• Linux: the binary is a fully static musl build; it runs on any
  x86_64 distribution.
• HEIC: the Rust build does not decode HEIC yet (a from-scratch
  decoder is in active development); it refuses HEIC loudly. The
  Python build handles HEIC today.
