feat(opencode): load OMO models from runtime opencode models (#5522)

* feat(opencode): load OMO models from runtime opencode models

Surface OAuth/Zen free models in OMO/OMO Slim pickers by running the
installed OpenCode CLI, with a 20s timeout and a toast when discovery fails.

* style: fix rustfmt and prettier for OMO runtime models

* fix(opencode): pass OPENCODE_CONFIG_DIR for runtime model discovery

Honor the configured OpenCode config directory when running
`opencode models`, including WSL UNC path translation. Also drop the
unused run_detected_tool_command wrapper that failed clippy.

* fix(opencode): satisfy Windows Clippy

* fix(opencode): bound runtime model discovery

* fix(opencode): address runtime model review feedback

* fix(ci): parenthesize unsafe kill expression
