2.15.1

Added

• Python and uv compatibility checks across supported Python 3.12–3.13,
  operating systems and current allowed dependencies, with advisory probes
  for newer interpreters.

Fixed

• Replace generic TUI command descriptions with actionable help shared by
  :help, autocomplete and the command palette. Keep command-root searches
  separate from commands that merely share a prefix.
• Return to the guided first task after connection, login and model selection
  finish, preserving the task and workspace draft. Cancelling the connection
  browser clears the pending return; running still requires validation,
  attached project context and an explicit Run action.
• Use a published, pinned setup-uv action in Python compatibility checks and
  exercise installer contracts in that workflow. Keep installation examples
  and recovery instructions on the supported Python 3.13 interpreter.
• Keep the headless output regression tests compatible with both older and
  current Click releases, including independent stdout and stderr capture.
• Select Python 3.13 in the installer, use monotonic timing without requiring
  an active event loop, and close agent configuration file handles promptly.
• Exit and clean up the TUI when terminal input closes, including piped input
  and detached POSIX terminals, instead of retaining an invisible session.
• Bound the live transcript to 3,000 rendered lines while retaining recorded
  messages for copy and export, and adjust reading anchors when lines roll off.
• Make local-model and DS4 warmup opt-in and preserve Ollama's server keep-alive
  policy unless a caller or environment setting explicitly overrides it.
• Reduce concurrent dependency builds, downloads and unpacking for contributor
  environments on laptops and smaller machines.
• Keep Windows task undo, redo and storage-failure rollback consistent with
  native file permissions. Poll idle Windows stdin pipes without blocking,
  and retain code-search content when only Git's POSIX grep is installed.
