Complete partial resolution system for @-prefixed partials

[galligan]

Description

The partial resolution system for loading @-prefixed partials from _partials/ directory is not implemented. Only a TODO stub exists in the code.

Expected Behavior

<!-- In a .rule.md file -->
{{> @common-header}}
{{> @security-guidelines}}
{{> @code-standards}}

Should load:

• .ruleset/src/_partials/common-header.md
• .ruleset/src/_partials/security-guidelines.md
• .ruleset/src/_partials/code-standards.md

Current Behavior

private setupPartialResolver(): void {
  // TODO: Implement @-prefixed partial loading from _partials/
}

Implementation Requirements

1. Resolve @name to _partials/name.md
2. Support nested partials
3. Handle missing partials gracefully
4. Cache loaded partials
5. Support both .md and .rule.md extensions
6. Recursive partial inclusion

Implementation Location

• /packages/core/src/compiler/handlebars-compiler.ts - setupPartialResolver method
• May need a separate partial-resolver.ts module

Test Requirements

• Test basic partial loading
• Test nested partial inclusion
• Test missing partial handling
• Test circular reference detection
• Test partial with variables
• Test partial caching

Status Update

This issue is still relevant but has been deprioritized due to the project migration from Mixdown to Rulesets. The partial resolution system needs to be reimplemented with the new architecture.

Current State

• The handlebars-compiler.ts file referenced no longer exists in the current codebase
• The project has migrated to a simpler, more focused architecture
• Partial/mixin support may need to be reconsidered in the context of the new Rulesets design

Next Steps

This feature should be re-evaluated once the core Rulesets functionality is stable. The implementation would likely be simpler in the new architecture.
