ruanslvchat : fix muse-glimmer detection of tool calls after EOM (#26879)0b1bad14f2026-08-11

{#
  Template: Muse Glimmer ATEM Chat Template
  Renders the ATEM tool-calling protocol: reasoning channel (to=self), tool
  channels (to=<tool>), and the user channel, plus tool definitions and the
  valid-recipient list in the system block.

  Whitespace note: every tag uses the {%- -%} / {{- -}} stripping markers, so
  the indentation below is purely for readability and contributes nothing to
  the rendered output.
