v1.9.0

This release adds Aura’s first real web research substrate, tightens Planner/Worker behavior, and continues cleaning out older prompt and research plumbing.
Highlights
Live Web Research
Aura now has a first-class research tool for current external information.

The Planner can call research_current_info when a user asks about current topics, recent releases, live documentation, or web search style questions. Aura performs the lookup through its own research layer and returns source/evidence data back to the model, so providers like DeepSeek can answer with current context even without native web search support.

This is the first version of Aura’s local browser-powered research path.

Playwright-Powered Browser Research
Added a new aura/research/ package with isolated modules for:

research models
search planning
limits/deadlines
browser-backed search/open behavior
research service orchestration
The implementation uses Playwright Python with headless Chromium. In development, Chromium is installed through Playwright. In packaged builds, the build pipeline now prepares the bundled browser/runtime assets so users do not need to set up a browser manually.

One Clean Planner Tool
Research is exposed to the Planner as a single tool:

research_current_info(query, constraints)

The Worker does not get browser/search primitives directly. This keeps web research as a controlled Planner capability instead of scattering browser tools across the coding workflow.

Old Research Plumbing Removed
Cleaned out the older hidden research/Tavily-style direction and replaced it with a clearer architecture:

one Planner-facing research tool
isolated backend implementation
no user API key required for search
no Node/MCP dependency in the default research path
fail-soft behavior when browser/search is unavailable
Prompt and Worker Cleanup
