v0.3.0

Token-saving response handling

This release focuses on minimizing the context-window cost of HTTP responses for AI agents:

• Automatic JSON minification — pretty-printed API responses are compacted before entering the agent context (20–40% token savings on indented APIs)
• jsonFilter parameter — extract only the fields you need from a JSON response using GJSON path syntax, e.g. name, items.#.id, {name,id}
• Binary response detection — binary bodies are summarized as [binary: image/png, 245891 bytes] instead of dumping raw bytes into context
• saveTo parameter — stream large or binary response bodies to a file (atomic write, no size limit) and return only a one-line summary; the agent can then read or grep the file
• maxResponseBytes parameter — per-request response size limit override
• Truncation notices now point the agent at saveTo to fetch the full body

New request capabilities

• Multipart file upload via the files (form field → local path) and formFields parameters
• --cookie-jar flag — opt-in in-memory cookie jar for session/login flows
• Base URL joining now also works for relative paths without a leading slash (api/users)

Maintenance

• MCP go-sdk upgraded v1.3.0 → v1.6.1; the tool now advertises the openWorldHint annotation
• Retry delay respects context cancellation
• Removed dead --log-* flags that were parsed but never used
