Release v3.2.1

[3.2.1] - 2026-07-29

• Release: Bumped package metadata and toyopuc.__version__ to 3.2.1.
• Release: GitHub Release drafts now prepend this version's changelog section to generated notes and repair a missing section on workflow reruns.
• Tooling: Pinned canonical profile fixture refreshes to plc-comm-computerlink-profiles v1.0.4, matching the embedded profile data used by this release.

BREAKING

• Library: Removed obsolete command upper-bit response flags and routes. Consumers must classify responses from their structural length and command contract instead of the removed flags.

Fixed

• Library: Write commands are never retried after a transport failure that may follow transmission; read-only classification is structural rather than dependent on the removed flags.
• Library: Relay response length decoding now handles a zero low byte correctly and rejects truncated or trailing response data exactly.
• Library: Profile catalog address bounds are advisory and do not reject transport sends; wire-format width checks remain.
