* fix: use SchemaCache to locate database metadata

* main:
 Refactor SchemaMetadataManager to use TableInfoCacheRef

 - Replace TableInfoManagerRef with TableInfoCacheRef in SchemaMetadataManager
 - Update DatanodeBuilder to pass TableInfoCacheRef to SchemaMetadataManager
 - Rename error MissingCacheRegistrySnafu to MissingCacheSnafu in datanode module
 - Adjust tests to use new mock_schema_metadata_manager with TableInfoCacheRef

* fix/schema-cache-invalidation: Add cache module and integrate cache registry into datanode

 • Implement build_datanode_cache_registry function to create cache registry for datanode
 • Integrate cache registry into datanode by modifying DatanodeBuilder and HeartbeatTask
 • Refactor InvalidateTableCacheHandler to InvalidateCacheHandler and move to common-meta crate
 • Update Cargo.toml to include cache as a dev-dependency for datanode
 • Adjust related modules (flownode, frontend, tests-integration, standalone) to use new cache handler and registry
 • Remove obsolete handler module from frontend crate

* fix: fuzz imports

* chore: add some doc for cahce builder functions

* refactor: change table info cache to table schema cache

* fix: remove unused variants

* fix fuzz

a617e0dbef feat: use cache kv manager for SchemaMetadataManager (#5053)
* feat: add cache for schema options

* fix/use-cache-kv-manager: Add cache invalidation handling to Datanode's heartbeat task

 • Implement InvalidateSchemaCacheHandler in heartbeat.rs to handle cache invalidation instructions.
 • Update HeartbeatTask constructor to accept cached_kv_backend and pass it to InvalidateSchemaCacheHandler.
 • Modify DatanodeBuilder to clone cached_kv_backend when creating schema_metadata_manager.
 • Refactor MetasrvCacheInvalidator in cache_invalidator.rs to reuse MailboxMessage for broadcasting to different channels.

* fix: only remove schema related cache entries

* chore: add more tests

* fix/use-cache-kv-manager: Moved InvalidateSchemaCacheHandler to a separate module

 • Extracted InvalidateSchemaCacheHandler and associated tests into a new file cache_invalidator.rs
 • Removed async_trait and CacheInvalidator related code from heartbeat.rs
 • Added cache_invalidator module declaration in handler.rs

* fix: unit tests

* fix/use-cache-kv-manager:
 Standardize TODO comment format in CachedKvBackend txn method
