Quick actions: user-defined agent actions alongside project scripts

[diegolmello]

Problem

Project scripts in the top bar only run terminal commands. Many repeated workflows are agent tasks, not shell commands: resolve merge conflicts, review the current branch, fix failing CI, write the PR description. Today each one means opening a thread, picking the provider and model, and retyping or pasting the same prompt.

Proposal

Let users define quick actions next to project scripts. Each quick action has:

• a name and icon
• a prompt or skill call (e.g. /code-review, or free text)
• an optional provider, model and effort (defaults to the current ones)
• a target: the current thread, a new thread, or a new thread in its own worktree
• a scope: per project or global

Running a quick action starts the agent with that prompt right away, the way a project script runs its command. Orca's quick actions are a good reference.

• [Feature]: Add one-click buttons for frequently used skills and insults #6612 (one-click skill/prompt buttons above the composer) sends text into the current thread's composer. This proposal adds launching a separate agent run with its own provider, model and target, and puts these actions next to project scripts.
• [Feature]: Saved snippets for frequently used prompts, with optional grouping #1547 (saved prompt snippets) inserts text into the draft without running anything.
