Add missing transform option to YAML autocomplete configuration and documentation

[Copilot]

The transform option was missing from the YAML autocomplete configuration schema, preventing users from disabling autocomplete output trimming even though the underlying system supported it.

Problem

Users reported that they couldn't set transform: false in their YAML autocomplete configuration to disable trimming of multiline completions. This was particularly problematic for models like Mamba-Codestral-7B served via vLLM, which generate better multiline completions when transformations are disabled.

The issue occurred because while the transform option existed in TabAutocompleteOptions and was respected by the autocomplete pipeline (defaulting to true), it was missing from the autocompleteOptionsSchema in the config-yaml package.

Solution

• Added transform: z.boolean().optional() to the autocompleteOptionsSchema in packages/config-yaml/src/schemas/models.ts
• Added documentation for the transform option in the config.yaml reference with usage examples

Example Usage

Users can now disable autocomplete transformations in their YAML config:

models:
  - name: mistralai/Mamba-Codestral-7B-v0.1
    provider: openai
    model: mistralai/Mamba-Codestral-7B-v0.1
    roles:
      - autocomplete
    autocompleteOptions:
      transform: false  # Disables trimming of multiline completions
      debounceDelay: 100
      template: "[SUFFIX]{{{suffix}}}[PREFIX]{{{prefix}}}"

Changes

• Added transform: z.boolean().optional() to autocompleteOptionsSchema
• Added comprehensive unit tests to verify the schema validation
• Added documentation to config.yaml reference explaining the transform option and its usage
• Added example showing transform: false in autocomplete configuration
• No breaking changes - the option is optional and backwards compatible

Testing

• All existing tests continue to pass
• New tests verify the schema accepts transform: true, transform: false, and configs without the transform option
• Manual verification confirms the fix resolves the original issue

Fixes #1.

@copilot can you add this to the docs? in the config.yaml reference

@copilot can you add this to the docs? in the config.yaml reference

I've added the transform option to the config.yaml reference documentation. The option is now documented in the autocompleteOptions section with a description explaining that it controls trimming of multiline completions, and I've included an example showing transform: false in the autocomplete configuration.

Changes are in commit 537fd7d.
