rust_tui_coder 1.0.0

# Project Improvements Summary

## Overview
This document summarizes all improvements made to the Rust TUI Coder project.

## 1. Fixed TUI Scrolling Issues 

### Problem
Users couldn't properly scroll up and down through the conversation history.

### Solution
- Improved scroll position calculation in `src/ui.rs`
- Added proper clamping logic to prevent scrolling past content boundaries
- Fixed auto-scroll to bottom when `usize::MAX` is set
- Improved visible height calculations for both conversation and tool logs
- Added better boundary checks to prevent overflow

### Changes Made
- Updated `src/ui.rs` lines 186-203 with improved scroll position logic
- Updated `src/ui.rs` lines 226-236 with tool logs scroll improvements
- Updated status message in `src/app.rs` to show all keyboard shortcuts

### Keyboard Controls
- Up/Down: Scroll up/down one line
- PgUp/PgDn: Scroll page up/down (10 lines)
- Home: Jump to top of conversation
- End: Jump to bottom of conversation

## 2. Fixed All Clippy Warnings 

### Problems Fixed
1. `tests/llm_tests.rs`: Removed useless comparison `count >= 0` for unsigned type
2. `tests/agent_tests.rs`: Removed unused variable warnings
3. `tests/agent_tests.rs`: Removed `assert!(true)` constant assertions

### Changes Made
- Fixed `test_estimate_token_count_whitespace()` to use proper assertion
- Fixed `test_agent_new()` to use `_agent` prefix for unused variable
- Fixed `test_agent_default()` to remove unnecessary assertion

### Result
```bash
cargo clippy --all-targets --all-features
#  Clean build with ZERO warnings
```
