Two new columns added to aibridge_token_usages: - cache_read_input_tokens (BIGINT, default 0) - cache_write_input_tokens (BIGINT, default 0) Migration backfills existing rows by extracting values from the metadata JSONB column (cache_read_input, input_cached, prompt_cached for reads (max value selected since only 1 should be set), cache_creation_input for writes). All references to data from metadata were updated to reference new columns. No other changes then changing where data is extracted from. Requires aibridge library version bump to include: https://github.com/coder/aibridge/pull/229 Fixes: https://github.com/coder/aibridge/issues/150
