It looks good for me. I'm not so sure how the newest versions of FastCS are implementing the attributes handling, but I can't see anything obviously wrong with the code. I'm happy to test it against real hardware whenever you're available to do so!

[shihab-dls]

This projects going to be updated to use FastCS 0.11 once #17 is in; would you mind rebasing over that branch, @hyperrealist? I can help, if there are ambiguous merge conflicts.

This is an integer valued enum. The values from PandA are strings.
@shihab-dls remind me what fastcs uses the names/values of an Enum for?

Pull request overview

This PR implements support for PandABlocks-server v4 “has_mode” tables by adding local/derived FastCS records needed for table append/streaming, and updates the project tooling (uv/tox-uv, CI, container, renovate/gitleaks, etc.).

Changes:

• Add table append support via a new Append command wrapper and NEXT_WRITE-controlled dispatch in table IO.
• Create additional records for has_mode tables (NEXT_WRITE, MODE, QUEUED_LINES, and a clear action).
• Modernize project tooling: uv-based workflows/tox config, Docker/devcontainer updates, renovate/gitleaks, and Python 3.13 CI/classifiers.
