- Consolidated `browserOpenSchema`, `browserCloseSchema`, and `browserRunSchema` into a single `browserSchema`.
- Simplified the `action` type definition to accept `'open' | 'close' | 'run'`.
- Updated schema validation tests to reflect the unified schema definition.
When a tool schema is a pure anyOf/oneOf (no own properties), push the intent field into each closed branch and skip the root sibling. The prior pass added properties: { i } / required: [i] next to the alternation; OpenAI strict sanitization then promoted that to a closed root that rejected every input. allOf members are sub-constraints, not alternatives, so they are no longer recursed.
Added normalizeTools tests for the union-shape path and a post-normalize strict-mode satisfiability test for the browser tool.
Fixes#3645
Updated intent tracing schema injection to add the intent field to anyOf/oneOf/allOf variants as well as the root schema.
Covered browser run/open variants after intent tracing normalization so closed unions stay satisfiable.
Fixes#3645
Encoded the browser tool as action-specific ArkType variants so run calls require code before execution.
Added schema-level regression coverage for code-less run calls.
Fixes#3645
