[Feature Request] Compact permission mode indicator option

Bug Description
Permission mode indicator takes too much horizontal space

The current labels — ⏵⏵ accept edits on (shift+tab to cycle), ⏵⏵ bypass permissions on (shift+tab to cycle), ⏸ plan mode on (shift+tab to cycle) — eat a lot of width
and the (shift+tab to cycle) hint is noise once you already know about the keybinding.

Suggested fix: replace the label with a single colored dot (with the full text on hover/focus or visible via a command like /mode):

• 🟢 normal (default, prompts for everything)
• 🟢 plan mode (read-only, very safe)
• 🟡 accept edits (auto-accepts file writes)
• 🔴 bypass permissions (no prompts — danger)

At minimum: a settings.json key like "ui.permissionModeIndicator": "dot" | "short" | "full" so power users can opt into a compact UI. Bonus: a
"ui.hidePermissionCycleHint": true to drop the (shift+tab to cycle) text once learned.

Thanks!
