docs: add Composer Images, Permission Modes, and Image feature row

- New 'Drag-and-Drop Images' section with composer screenshot.
- New 'Permission Modes' section spelling out default / acceptEdits /
  auto / bypassPermissions / plan and what each one auto-allows. Auto
  mode in particular lets file edits and Bash through without prompting,
  with sub-agents (Task) still requiring explicit approval.
- Features table picks up a 'Composer Images' row.

+### 🖼️ Drag-and-Drop Images
+
+Paste or drag images straight into the composer — bug screenshots, mockups, error dialogs, hand-drawn diagrams. Claude reads them inline alongside your prompt; no file upload, no tool call dance, no hosting step.

+
+### 🛡️ Permission Modes
+
+Pick how aggressively Claude can act without asking:
+
+- **Default** — every tool use prompts for approval (the CLI's standard).
+- **Accept Edits** — file edits go through automatically; everything else still asks.
+- **Auto** — file edits AND shell commands run without a prompt; only sub-agent spawns (`Task`) and explicit kill-switches still ask. One step short of full bypass — convenient when you trust the run, safer than the nuclear option.
+- **Bypass Permissions** — the nuclear option; no prompts at all. Use when you really mean it.
+- **Plan** — read-only; refuses any tool that would mutate state.
+
+Switch the mode globally from Settings or per-session from the chat dropdown next to the model selector.

 ### 🎨 Settings & Customization
