v0.29.0-beta.3

Delta since previous beta (v0.29.0-beta.2) — 2 new changesets.

Patch Changes

• Fix the write and edit MCP tools failing with a schema-conversion error on constrained-decoding hosts like LM Studio (Error resolving ref #/definitions/__schema0). Their frontmatter field advertised a recursive JSON Schema ($ref: "#/definitions/__schema0"); LM Studio — and some function-calling APIs like Gemini — can't resolve an intra-schema $ref in a tool definition and reject the whole tool. Claude and most MCP clients resolve it leniently, so this only surfaced on local-inference hosts.

  The frontmatter value now advertises a flat, $ref-free JSON Schema (scalar | array | object | null), while a runtime refinement re-applies the exact recursive validation — so accepted/rejected inputs are unchanged for every client and every write path (nested null is still rejected, deep nesting and heterogeneous arrays still accepted). Added a test that compiles every tool's input and output schema and fails if any emits a $ref, so this can't silently regress.
