* feat: add close-first soft-drop table flow
Soft-drop now tombstones table metadata and closes datanode regions instead of
issuing physical drop requests, while preserving hard-drop cleanup semantics and
blocking conflicting drops of recreated table names.

* fix: remove redundant spawn_datanode_query in RegionServer::handle_read
The outer `spawn_datanode_query` wrapped `handle_read_inner` on the
same runtime, creating a nested spawn that consumed query runtime
threads unnecessarily under concurrent read load. The gRPC handler
already provides runtime isolation, so the inner call is sufficient.

directly instead of spawning onto the datanode query runtime

* feat: support reporting env vars in heartbeat messages to metasrv

configured, the specified environment variable values are read at startup
and sent to metasrv in every heartbeat via the `extensions` map. Metasrv
extracts and stores them in `NodeInfo` for use in routing decisions
(e.g. AZ-aware region placement).
- Add `EnvVars` helper in `common/meta/src/datanode.rs` following the
existing `GcStat` extension pattern with `into_extensions`/`from_extensions`
- Add `env_vars: HashMap<String, String>` field to `NodeInfo` in
`common/meta/src/cluster.rs` with `#[serde(default)]` for backward compat
- Add `heartbeat_env_vars: Vec<String>` config field to `DatanodeOptions`,

heartbeat tasks (`datanode/src/heartbeat.rs`, `frontend/src/heartbeat.rs`)

- Rename `build_wal_options_allocator` to `build_wal_provider`

* feat(meta-srv): implement region allocation for repartition procedure
This commit implements the region allocation phase of the repartition procedure,
which handles allocating new regions when a table needs to be split into more partitions.
Key changes:
- Refactor `RegionRoutesAllocator::allocate` to accept `(region_number, partition_expr)` tuples
for more flexible region number assignment
- Simplify `AllocationPlanEntry` by removing `regions_to_allocate` and `regions_to_deallocate`
fields (now derived from source/target counts)
- Add `convert_allocation_plan_to_repartition_plan` function to handle allocation, equal,
and deallocation cases
- Fix `RepartitionPlanEntry::allocate_regions()` to return target regions (was incorrectly
returning source regions)
- Implement complete `AllocateRegion` state with:
- Region route allocation via `RegionRoutesAllocator`
- WAL options allocation via `WalOptionsAllocator`
- Operating region registration for concurrency control
- Region creation on datanodes via `CreateTableExecutor`
- Table route metadata update
- Add `TableRouteValue::max_region_number()` helper method
- Add comprehensive unit tests for plan conversion and allocation logic
