* feat: table semantic layer identity (Phase 1)
Attach a thin layer of semantic metadata to ingested tables via the existing
`table_options` slot, so machine consumers (LLM agents, alert/dashboard builders,
MCP servers, ETL) can align a table with the observability concept it stands for
without guessing from column names. See docs/rfcs/2026-05-28-table-semantic-layer.md.
Phase 1 (identity) only:
- New `table::requests::semantic` module: the `greptime.semantic.*` vocabulary
(signal/source/source_version/pipeline + trace/metric/log/resource-scope keys,
defined now, populated by later phases), value constants, the internal
`greptime.internal.semantic.per_table_index` transport key (reserved for Phase 2,
deliberately outside the public namespace), and `is_semantic_option_key`.
- `validate_table_option` accepts the `greptime.semantic.*` prefix, so the keys are
valid both on the auto-create path and on explicit `CREATE TABLE ... WITH (...)`.
- `fill_table_options_for_create` copies every semantic ctx extension into the new
table's options (prefix passthrough alongside the fixed allowlist).
- Frontend stamps identity on the context at each ingest entry: OTLP metrics
(metric/opentelemetry), traces (+pipeline, has_events/has_links/conventions for
the v1 model), logs (log/opentelemetry), and Prometheus remote write
(metric/prometheus, metadata_quality=inferred). OTLP metric metadata_quality is
left for Phase 2 (declared).
- Trace identity is stamped only on the main span table; the derived
`_services` / `_operations` lookup tables keep the unstamped context and carry no
semantic identity (cross-table relationships are out of scope).
Semantic options appear in SHOW CREATE TABLE (like table_data_model /
otlp_metric_compat) and in information_schema, so an LLM inspecting a table sees its
semantics directly.
Tests: unit (validation prefix + internal-key rejection, ctx passthrough) and
integration assertions that the common keys land for OTLP metrics (metric-engine
logical table), traces, logs, and Prometheus remote write; SHOW CREATE goldens
updated.

* feat: switch partition tree to bulk
Signed-off-by: evenyag <realevenyag@gmail.com>
* chore: keep partition tree memtable for migration test
Restore PartitionTreeMemtable construction when memtable.type=partition_tree
is explicit, and move the sparse-encoding bulk override into the default
(no explicit memtable.type) arm so phase 2's memtable.type=bulk wins on
reopen. Rewrite test_reopen_time_series_sparse_memtable_with_bulk to use a
metric-engine-shaped schema and sparse-encoded rows with WriteHint::Sparse,
so the test actually exercises a PartitionTreeMemtable in phase 1 and
verifies WAL replay into the new BulkMemtable on reopen without flushing.

* chore: drop partition tree memtable from runtime
Re-apply the unconditional sparse-encoding override in
`MemtableBuilderProvider::builder_for_options` and route the
`MemtableOptions::PartitionTree` arm to `BulkMemtable` with a deprecation
warning. After this change, `PartitionTreeMemtableBuilder` is no longer
reachable from the engine runtime; benchmarks still reference the type.
Remove `test_reopen_time_series_sparse_memtable_with_bulk` and the
`put_sparse_rows` helper added in the previous commit — that test only
existed to validate the PartitionTree -> Bulk reopen migration and is
unnecessary now that the override is in place.

* refactor(mito2): move timestamp_array_to_i64_slice into read module
Relocate the timestamp_array_to_i64_slice helper from
memtable/partition_tree/data.rs to the read module so that the read
path no longer depends on the partition_tree internals. All call sites
(both inside and outside the partition_tree module) now import from
crate::read.

* refactor(mito2): use TimeSeriesMemtableBuilder in time_partition tests
The time_partition tests use the memtable builder purely as a generic
backend for the TimePartitions write/scan paths; nothing in them is
specific to the partition-tree memtable. Switch the seven affected
tests to TimeSeriesMemtableBuilder so the tests no longer depend on
PartitionTreeMemtableBuilder.

* chore(mito2): delete PartitionTreeMemtable implementation
The runtime already falls back to BulkMemtable for the PartitionTree
variant. Drop the now-unreachable implementation, its metrics, the
partition_tree benchmarks, the metric-engine Unsupported fallback in
bulk_insert.rs, and the test helpers that only existed for the deleted
module.
MemtableOptions::PartitionTree, its parsing, the runtime fallback, the
store-api MEMTABLE_PARTITION_TREE_* constants, and the SQL fixtures
remain so existing region options keep round-tripping.

* refactor(mito-codec): drop skip_partition_column parameter
PartitionTreeMemtable was the only caller passing
skip_partition_column=true; every other caller passes false. Now that
the partition_tree module is gone, the parameter is uniformly false
and the guard branch is dead. Drop the parameter from the trait method
and both impls, remove the guard and the is_partition_column helper,
and update the four remaining call sites in mito2 plus the bench.

the SST format to flat in addition to clearing the memtable type.
