feat(protocol): reconcile schemas with factory-mono-alpha source of truth

Adds missing fields/enum members detected by mono's verify-sdk-parity
audit so the SDK is bit-equivalent to mono's wire schemas:

- enums.ts: add ModelID entries ORIEL_0601, OXIDE_0601, OXBOW_0601,
  OCELOT_0601 (Olympus families released after the previous port).
- general-settings.ts: add McpAutonomyUrlOverrideSchema +
  mcpAutonomyUrlOverrides on ManagedSettingsBaseSchema, and
  dismissedNewModels on GeneralSettingsSchema.
- daemon/droid.ts:
  - DaemonGetGitDiffDataSchema: add committedDiff / committedFiles /
    committedTotalAdditions / committedTotalDeletions for the
    committed-only diff section the frontend renders.
  - DaemonGetGitDiffRequestParamsSchema: add statsOnly.
  - DaemonGetWorkspaceFileContentRequestParamsSchema: add encoding
    (utf8|base64) for binary file previews.
  - DaemonGetWorkspaceFileContentResultSchema: add encoding, mimeType,
    isBinary so the frontend can guard binary content properly.

After this change factory-mono-alpha reports 265/265 schema MATCH and
0 MISMATCH against @factory/droid-sdk/protocol.
