feat: Add binary path resolution and Docker support (v0.1.0)

This release adds intelligent binary discovery and Docker support to Tendril,
making it more flexible and cross-platform compatible.

## Features

### Binary Path Resolution
- Intelligent binary discovery with smart fallbacks
- Explicit user configuration via gitea_mcp_binary_path setting
- Standard system paths (/usr/local/bin, /usr/bin)
- User home directories (~/.local/bin, ~/.cargo/bin, ~/bin)
- Platform-specific paths (/opt/homebrew/bin on macOS M-series)
- System PATH environment variable search
- Robust WASM sandbox handling for filesystem checks
- Comprehensive error messages with troubleshooting guidance
- Removed hardcoded /usr/local/bin/gitea-mcp path

### Docker Support
- New use_docker configuration option for containerized deployment
- New docker_image configuration for custom images (default: gitea/gitea-mcp-server:latest)
- Automatic docker binary detection at /usr/bin/docker or other standard locations
- Proper gitea-mcp command-line flag formatting (-token, -t stdio, -host, -insecure)
- STDIO communication through Docker containers

### Cross-Platform Support
- Linux: Standard system and user paths
- macOS Intel: Same as Linux
- macOS M-series (ARM64): Optimized for /opt/homebrew/bin
- Windows: Program Files paths (code ready, untested)
- Proper PATH separator handling (: on Unix, ; on Windows)

## Bug Fixes

- Fixed WASM sandbox filesystem access limitations
- Corrected Docker image name to gitea/gitea-mcp-server:latest
- Fixed Docker command flag formatting for gitea-mcp arguments
- Improved error handling with helpful resolution steps

## Documentation

- Updated README.md with Docker mode examples and configuration reference
- Expanded DEVELOPMENT.md with architecture and testing roadmap
- Updated PROJECT_STATUS.md with v0.1.0 feature status
- Updated configuration with all new options and detailed comments
- Added comprehensive inline code comments

## Testing

- Binary mode auto-detection: Tested and working
- Binary mode custom path: Tested and working
- Docker mode with default image: Tested and working
- Self-hosted Gitea instances: Tested and working
- Self-signed certificate support: Tested and working

## Files Changed

- src/mcp_server_gitea.rs: Core extension (~350 lines)
- configuration/default_settings.jsonc: New settings
- configuration/installation_instructions.md: Updated guide
- README.md: Expanded documentation
- DEVELOPMENT.md: Complete developer guide
- PROJECT_STATUS.md: Updated status
- .gitignore: Added comprehensive ignore file

## Breaking Changes

None - fully backward compatible.

## Next Steps (v0.2.0)

- Cross-platform testing
- Interactive configuration wizard
- Performance optimizations
- Marketplace publication

+# Tendril Quick Start Guide
+
+**TL;DR**: Get Tendril working in 5 minutes.
+
+## Prerequisites
+
+```bash
+# 1. Install Rust (if not already installed)
+curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
+
+# 2. Download and install gitea-mcp binary
+wget https://gitea.com/gitea/gitea-mcp/releases/download/v1.0.0/gitea-mcp-linux-amd64
+chmod +x gitea-mcp-linux-amd64
+sudo mv gitea-mcp-linux-amd64 /usr/local/bin/gitea-mcp
+
+# Verify
+/usr/local/bin/gitea-mcp --help
+```
+
+## Generate Gitea Token
+
+1. Log in to your Gitea instance
+2. Settings → Applications → Authorize New Application
+3. Name: "Zed MCP"
+4. Check repository permissions
+5. Copy the token
+
+## Install in Zed (Dev Extension)
+
+```bash
+# 1. Open Zed
+# 2. Extensions → Install Dev Extension
+# 3. Select the tendril directory
+# 4. Wait for Zed to compile (a few seconds first time)
+```
+
+## Configure Zed
+
+Add to your `settings.json`:
+
+```json
+{
+  "context_servers": {
+    "tendril-gitea-mcp": {
+      "settings": {
+        "gitea_access_token": "YOUR_TOKEN_HERE"
+      }
+    }
+  }
+}
+```
+
+## Test It
+
+1. Open Zed's Assistant (Cmd+K)
+2. Type: `list my repositories`
+3. Done! 🎉
+
+---
+
+## Configuration Options
+
+```json
+{
+  "context_servers": {
+    "tendril-gitea-mcp": {
+      "settings": {
+        "gitea_access_token": "required",           // Your token
+        "gitea_host": "https://git.example.com",   // Self-hosted Gitea
+        "gitea_insecure": false,                    // Self-signed certs
+        "gitea_port": 8080,                         // SSE mode port
+        "use_sse": false                            // Use SSE instead of STDIO
+      }
+    }
+  }
+}
+```
+
+## Troubleshooting
+
+| Problem | Solution |
+|---------|----------|
+| "failed to spawn command" | Make sure `/usr/local/bin/gitea-mcp` exists: `ls -l /usr/local/bin/gitea-mcp` |
+| Extension not loading | Check Zed logs: `zed: open log` |
+| Auth errors | Verify token and permissions, regenerate if needed |
+| SSE mode issues | Try STDIO mode: set `"use_sse": false` |
+
+## Useful Commands
+
+```bash
+# Test the binary
+/usr/local/bin/gitea-mcp --help
+
+# View logs
+tail -f ~/.gitea-mcp/gitea-mcp.log
+
+# Check Zed logs (in Zed)
+zed: open log
+
+# Rebuild extension
+cargo build --release
+```

+## What Tendril Does
+
+Tendril is a **Zed extension** that connects to a **gitea-mcp server** running on your system.
+
+```
+Zed (with Tendril extension)
+        ↓
+gitea-mcp binary (at /usr/local/bin/gitea-mcp)
+        ↓
+Gitea Instance (your self-hosted or public Gitea)
+```
+
+The extension lets you interact with Gitea repositories, issues, PRs, and more directly from Zed's Assistant panel using natural language.
