feat(vefaas): add vefaas_cli_sdk module and refactor deploy workflow

## Summary

This is a major refactoring of the veFaaS MCP Server to introduce a new
vefaas_cli_sdk module ported from vefaas-cli, providing better project
detection, deployment workflow, and configuration management.

## New Components

### vefaas_cli_sdk module (new)
- **deploy.py**: Core deployment logic
  - VeFaaSClient: Unified API client with error handling
  - Package directory with .vefaasignore support
  - Static site deployment with Caddyfile generation
  - Full deployment workflow (create/update function, build, release, poll status)

- **detector.py**: Project detection module
  - Auto-detect framework (Next.js, Vite, FastAPI, Flask, Streamlit, etc.)
  - Detect runtime, build command, start command, and port
  - Support for Node.js, Python, and static site projects

- **config.py**: Configuration management
  - Read/write .vefaas/config.json (vefaas-cli compatible)
  - Read/write vefaas.yaml (legacy MCP format)
  - Region-aware configuration linking

## Tool Changes

### deploy_application (enhanced)
- Now the PRIMARY deployment tool - one command to deploy
- Handles full workflow: detect → build → package → upload → create/update → release
- Region-aware configuration: only uses cached IDs if region matches
- Explicit build_command validation for non-Python runtimes
- Clear error messages with actionable next_action guidance

### detect_project (enhanced)
- Uses new detector module for accurate framework detection
- Returns comprehensive project configuration

### get_function_detail / pull_function_code (enhanced)
- Better error handling for optional fields
- Returns SourceType for early validation

### Removed tools
- create_vefaas_application (merged into deploy_application)
- poll_vefaas_application_status (handled internally)
- list_vefaas_application_templates (no longer needed)
- get_vefaas_application_template (no longer needed)

## Test Updates
- Added tests for new vefaas_cli_sdk module
- Updated existing tests for refactored tools
- Added region-aware deployment tests

## Dependencies
- Added 'pathspec' for .vefaasignore pattern matching
- Added 'pyyaml' for YAML config file support
