Add symbol metadata to outlined files

[andrew]

Add top-level declaration metadata to outlined files without parsing source a second time. Each outlined File now includes ordered Symbol values with a name, kind, one-based line, and language-aware export status.

Standard symbol captures cover every existing language query, including Go capitalization, JavaScript and TypeScript exports and CommonJS assignments, and Python underscore visibility.

Pull request overview

Adds symbol metadata capture to the outlining pipeline so each outlined File can expose an ordered list of top-level Symbol declarations (name, kind, one-based line, export status) without re-parsing the source.

Changes:

• Introduces Symbol extraction from existing tree-sitter query matches and attaches it to outlined results.
• Extends language queries (queries/*.scm) to capture top-level symbols across supported languages.
• Plumbs symbols through Pack output and adds comprehensive multi-language tests.
