The monolith->package split landed while #558 was adding provider-aware web
search to toolorchestra.py upstream. Rebasing resolved that as delete-vs-modify,
which would have silently dropped the feature: the package always routed search
to Anthropic. Port it -- search now follows cloud_endpoint (openai-web-search /
gemini-web-search / anthropic-web-search), with the matching worker types,
per-search cost surcharges, and pool validation.
_TOOLORCH_SEARCH_TYPES replaces the scattered == "anthropic-web-search" checks,
so the one-shot guard and the "needs a solver" rule now cover every search type
rather than just the Anthropic one -- previously a search worker could have been
picked as the synthesis fallback.
Also, to get back under the ruff gate CI now enforces (it landed in the 95
commits we were behind): formatting, import order, and one real bug -- calculator
had "abs" twice in the same dict literal, and eval_backend had four imports
stranded below a function body.
The build_orchestrator_sft driver test read OJ_DATA_ROOT from the ambient
environment, so it wrote to the real experiments tree instead of tmp_path for
anyone who had sourced .env. Drop the var in the test.
