Claude e0f856fd11 Add Liquid to Ruby compiler for optimized template rendering ...

This adds a new `compile_to_ruby` method to Liquid::Template that compiles
Liquid templates to pure Ruby code. The compiled code can be eval'd to create
a proc that renders templates without needing the Liquid library at runtime.

## Features

- Compiles all standard Liquid tags: if/unless/case, for, assign, capture,
  cycle, increment/decrement, raw, echo, break/continue, comment, tablerow
- Compiles variable expressions with filter chains to direct Ruby method calls
- Supports static partial inlining ({% render %} and {% include %} with string
  literals are loaded and compiled at compile time)
- Dynamic partial support via runtime callbacks (__render_dynamic__, __include_dynamic__)
- Debug mode with source comments for error tracing (lightweight source map)
- SourceMapper utility to trace runtime errors back to Liquid source

## Optimization Opportunities

The compiled Ruby code has significant performance advantages:

1. No Context object - variables accessed directly from assigns hash
2. No filter invocation overhead - direct Ruby method calls
3. No resource limits tracking - no per-node render score updates
4. No stack-based scoping - uses Ruby's native block scoping
5. Direct string concatenation - no render_to_output_buffer abstraction
6. Native control flow - break/continue use Ruby's throw/catch
7. No to_liquid calls - values used directly
8. No profiling hooks - no profiler overhead
9. No exception rendering - errors propagate naturally

## Usage

```ruby
template = Liquid::Template.parse("Hello, {{ name }}!")
ruby_code = template.compile_to_ruby
render_proc = eval(ruby_code)
result = render_proc.call({ "name" => "World" })
# => "Hello, World!"

# With debug mode for error tracing:
ruby_code = template.compile_to_ruby(debug: true)
```

## Limitations

- Dynamic {% render %} and {% include %} require runtime callback methods
- Custom tags need explicit compiler implementations
- Custom filters must be available at runtime
