Use one shared action/model path when behavior is exposed through multiple entrypoints.

Shared entrypoints

When a behavior is exposed through multiple surfaces, implement one shared action/model path and verify every entrypoint that should invoke it.

Common entrypoints include:

• keyboard shortcut
• command palette
• context menu
• CLI/socket command
• settings UI
• debug menu

Do not patch one surface while leaving the others with duplicated logic.
