Add todo tool for task management and enhance CLI features

- Introduced a new `todo_tool.py` for planning and tracking multi-step tasks, enhancing the agent's capabilities.
- Updated CLI to include a floating autocomplete dropdown for commands and improved user instructions for better navigation.
- Revised toolsets to incorporate the new `todo` tool and updated documentation to reflect changes in available tools and commands.
- Enhanced user experience with new keybindings and clearer command descriptions in the CLI.

 The interactive CLI uses:

-- **KawaiiSpinner** (in run_agent.py) - Animated feedback during API calls and tool execution
+- **prompt_toolkit** - For fixed input area with history, `patch_stdout`, slash command autocomplete, and floating completion menus
+- **KawaiiSpinner** (in run_agent.py) - Animated kawaii faces during API calls; clean `┊` activity feed for tool execution results
 
 Key components:
 - `HermesCLI` class - Main CLI controller with commands and conversation loop
+- `SlashCommandCompleter` - Autocomplete dropdown for `/commands` (type `/` to see all)
 - `load_cli_config()` - Loads config, sets environment variables for terminal
 - `build_welcome_banner()` - Displays ASCII art logo, tools, and skills summary
+
+CLI UX notes:
+- Thinking spinner (during LLM API call) shows animated kawaii face + verb (`(⌐■_■) deliberating...`)
+- When LLM returns tool calls, the spinner clears silently (no "got it!" noise)
+- Tool execution results appear as a clean activity feed: `┊ {emoji} {verb} {detail} {duration}`
+- "got it!" only appears when the LLM returns a final text response (`⚕ ready`)
+- The prompt shows `⚕ ❯` when the agent is working, `❯` when idle
+- Pasting 5+ lines auto-saves to `~/.hermes/pastes/` and collapses to a reference
+- Multi-line input via Alt+Enter or Ctrl+J
 - `/commands` - Process user commands like `/help`, `/clear`, `/personality`, etc.

+**Special case: tools that need agent-level state** (like `todo`):
+If your tool needs access to the AIAgent instance (e.g., in-memory state per session), intercept it directly in `run_agent.py`'s tool dispatch loop *before* `handle_function_call()`. Add a fallback error in `handle_function_call()` for safety. See `todo_tool.py` and the `if function_name == "todo":` block in `run_agent.py` for the pattern. For RL environments, add the same intercept in `environments/agent_loop.py`.
