[FEATURE] Persistent, adjustable approval preferences for bash command prompts during multi-agent sessions

Preflight Checklist

• [x] I have searched existing requests and this feature hasn't been requested yet
• [x] This is a single feature request (not multiple features)

Problem Statement

The current bash command approval flow offers:

• 1) Yes
• 2) No
• Occasionally Yes, don't ask again
• Ctrl-C to abort

This works well for single-agent sessions, but becomes disruptive when running multiple agents in parallel. Interrupting one agent's prompt can block or cancel the entire session, and the binary yes/no model doesn't allow nuanced feedback mid-run.

Proposed Solution

Add a third persistent option to every bash command prompt:
1) Yes
2) No
3) Adjust preference and continue
Option 3 would:

• Open a short inline prompt where the user can describe a rule (e.g. "always approve git status but ask for git commit")
• Apply that rule immediately for the remainder of the session
• Optionally persist it to settings.json auto-approve rules

Use Case Example

You launch 3 agents in parallel: one running tests, one refactoring a module, one updating a schema. Mid-run, the refactoring agent hits a git commit prompt and waits. You want to approve it — but you also want to tell it "don't ask me about git commit again this session, I trust it". Your only options today are:

• Say yes (asked again next commit)
• Say "yes, don't ask again" (too broad — now nothing asks)
• Hit Ctrl-C (kills the agent, loses all progress)

With option 3, you'd type: "approve git commit for the rest of this session" — the agent continues, the rule applies, and the other two agents are unaffected.
