v0.2.0 — attached-file handling

Added

• Attached-file handling (Step 1a in refine.md). When $ARGUMENTS contains file paths (CSV, PNG/JPG/screenshot, PDF, JSON, log, etc.), the refiner now opens them with the appropriate tool and surfaces what it finds — column names and sample rows for tabular data, visible UI/layout/text for images, summarized content for documents, structure for code/config. File paths are carried verbatim into the refined prompt's Context section, and promoted to Goal/Steps/Approach when the file is the central input (e.g. a Siteimprove CSV to process or a PNG of a UI design to replicate).

Changed

• README badge and Releases section bumped to v0.2.0.
• "How it works" procedure in README updated to mention attached-file handling.
