Allow Run Now on an automation with one-time additional context

Add a way to run an existing automation ad-hoc with one-time additional context.

Today, if I have an automation that is mostly reusable but needs run-specific context, the workflow is awkward:

1. Edit the automation prompt to include the temporary context.
2. Run it, or paste the modified prompt into a new chat.
3. Remove the temporary context afterward so the saved automation is not permanently changed.

This makes automations less useful as reusable workflows. The saved automation prompt is the stable procedure, but many real runs need a small amount of extra context, such as:

• “Run the release-review automation, but focus on this PR.”
• “Run the repo-maintenance automation, but include this error log.”
• “Run the weekly summary automation now, but also consider this incident.”
• “Run the code-review automation against this branch/commit/range.”

The ideal UX would be something like:

• A Run Now... action that opens a short input field for optional run-specific context.
• The automation starts a new run using:
• the saved automation prompt,
• plus the one-time context,
• without modifying the saved automation definition.
• The resulting thread should show both the base automation and the extra context used for that run.

This is different from editing the automation itself because the extra context should not persist. It is also different from just starting a normal chat because I want to reuse the automation’s configured prompt, project/worktree, model/settings, and any future automation-specific behavior.

Those cover adjacent automation execution and context problems, but I could not find an issue specifically for “Run Now with temporary additional context.”
