Feature Request: Rejection Comments in permissions.yaml

Problem

When a tool call is rejected (manually or via permissions.yaml), the model doesn't understand why and often repeats the same mistake. Rules in .continuerules are often ignored after several tool calls.

Proposed Solution

Add optional comment/hint syntax to permissions.yaml that gets sent to the model when a tool is rejected:

exclude:
  - Bash(*cd *, "Don't use 'cd'. Set correct 'cwd' parameter instead.")
  - Bash(*&&*, "Don't chain commands with '&&'. Run commands separately.")
  - Bash(*git push*, "Never push automatically. User will push manually.")
  - Bash(*rm -rf*, "Dangerous command. Ask user for confirmation first.")

Benefits

1. Persistent guidance — hints are always sent on rejection, not forgotten like rules
2. Context-aware — model receives explanation at the exact moment of error
3. Configurable — users can customize messages per tool pattern
4. DRY — no need to repeat same instructions in chat

Current Behavior

exclude:
  - Bash(*cd *)

→ Model receives generic rejection → repeats mistake

Desired Behavior

exclude:
  - Bash(*cd *, "Use 'cwd' parameter instead of 'cd' command")

→ Model receives rejection + hint → adjusts behavior
