dbt-core v1.12.1

Added 1

Add OpenTelemetry span instrumentation for node and hook execution, gated behind the --snowflake-projects-otel flag (off by default)

Fixed 4

Fix dbt build node count being inflated when unit tests are selected by adding the unit test count to num_nodes exactly once instead of on every dequeue
Stop resolving a unit test's tested model eagerly at parse time and resolve it only in the single deterministic post-parse pass so resolution no longer depends on filesystem parse order
Re-parse adapter macros from the installed adapter package after loading a Fusion-generated manifest, ensuring the user's installed dbt-adapter version is used instead of Fusion's compile-time bundled copy
Fix OpenTelemetry hook spans by naming them by hook and transaction phase, skipping calls that run no hooks, and adding node context and status

Add OpenTelemetry span instrumentation for node and hook execution, gated behind the --snowflake-projects-otel flag (off by default) (#11367)

Fix dbt build node count ("X of Y") being inflated when unit tests are selected, by adding the unit test count to num_nodes exactly once instead of on every dequeue while run_count is still 0 (#11185)
Stop resolving a unit test's tested model eagerly at parse time; resolve it only in the single deterministic post-parse pass so resolution no longer depends on filesystem parse order at all (deeper fix for (#11139)
Re-parse adapter macros from the installed adapter package after loading a Fusion-generated manifest, ensuring the user's installed dbt- version is used instead of Fusion's compile-time bundled copy (#15527)
Fix OpenTelemetry hook spans: name them by hook and transaction phase, skip calls that run no hooks, and add node context and status. (#11367)
