chore(qmd): bump version 2.1.1-oivo.0 -> 2.2.0-oivo.0

Minor bump justified by additive API in i-1rqixh6m / i-loazq6ze:

- New exported type: TokenCounter
- chunkDocumentByTokens gains optional 8th param (tokenizer?)
- searchVec/hybridQuery/structuredSearch gain optional embedProvider param
- SDK SearchOptions/StoreOptions/VectorSearchOptions gain embedProvider field
- New AutoFallbackEmbeddingProvider wrapper
- Re-exports: createEmbeddingProvider, OpenAIEmbeddingsProvider,
  CircuitBreaker, AutoFallbackEmbeddingProvider, etc.

All additive — backward-compat preserved (zero env-vars / zero options =
identical pre-patch behavior, local llama-cpp path unchanged).

Consumers: cli/package.json uses "file:../vendor/qmd" so no semver
resolution actually runs at install time on the fleet. This bump is
informational metadata for changelog tooling and any future caller that
reads the field directly.
