✨ Improved RSpec Support

### Added

- `TreeHaver::RSpec::TestableNode` - A testable node class for creating mock TreeHaver::Node instances
  in tests without requiring an actual parser backend. Available via `require "tree_haver/rspec/testable_node"`
  or automatically when using `require "tree_haver/rspec"`.
  - `TestableNode.create(type:, text:, ...)` - Create a single test node
  - `TestableNode.create_list(...)` - Create multiple test nodes
  - `MockInnerNode` - The underlying mock that simulates backend-specific nodes
  - Top-level `TestableNode` constant for convenience in specs
- **Fully Dynamic Tag Registration** in `TreeHaver::BackendRegistry`:
  - `register_tag(tag_name, category:, backend_name:, require_path:)` - Register a complete dependency tag
    with lazy loading support. External gems can now get full RSpec tag support without any hardcoded
    knowledge in tree_haver.
  - `tag_available?(tag_name)` - Check if a tag's dependency is available, with automatic lazy loading
    via the registered `require_path`
  - `registered_tags` - Get all registered tag names
  - `tags_by_category(category)` - Get tags filtered by category (:backend, :gem, :parsing, :grammar, :engine, :other)
  - `tag_metadata(tag_name)` - Get full metadata for a registered tag
  - `tag_summary` - Get availability status of all registered tags

### Changed

- **Fully Dynamic Backend Availability** in `BackendRegistry` and `DependencyTags`:
  - `register_tag` now dynamically defines `*_available?` methods on `DependencyTags` at registration time
  - External gems automatically get availability methods when they call `register_tag`
  - No changes to tree_haver are needed for new external backend gems
  - Built-in backends (prism, psych, citrus, parslet) retain explicit methods
  - `summary` method dynamically includes registered backends from BackendRegistry
  - `backend_availability_methods` and `backend_tags` hashes are built dynamically
- RSpec exclusion filters fo... (continued)
