### Enhance Pipeline Processing for One-to-Many Transformations
- **Support One-to-Many Transformations**:
- Updated `processor.rs`, `etl.rs`, `vrl_processor.rs`, and `greptime.rs` to handle one-to-many transformations by allowing VRL processors to return arrays, expanding each element into separate rows.
- Introduced `transform_array_elements` and `values_to_rows` functions to facilitate this transformation.
- **Error Handling Enhancements**:
- Added new error types in `error.rs` to handle cases where array elements are not objects and for transformation failures.
- **Testing Enhancements**:
- Added tests in `pipeline.rs` to verify one-to-many transformations, single object processing, and error handling for non-object array elements.
- **Context Management**:
- Modified `ctx_req.rs` to clone `ContextOpt` when adding rows, ensuring correct context management during transformations.
- **Server Pipeline Adjustments**:
- Updated `pipeline.rs` in `servers` to handle transformed outputs with one-to-many row expansions, ensuring correct row padding and request formation.

* feat/allow-one-to-many-pipeline:
Add one-to-many VRL pipeline test in `http.rs`
- Introduced `test_pipeline_one_to_many_vrl` to verify VRL processor's ability to expand a single input row into multiple output rows.
- Updated `http_tests!` macro to include the new test.
- Implemented test scenarios for single and multiple input rows, ensuring correct data transformation and row count validation.

### Add Tests for VRL Pipeline Transformations
- **File:** `src/pipeline/src/etl.rs`
- Added tests for one-to-many VRL pipeline expansion to ensure multiple output rows from a single input.
- Introduced tests to verify backward compatibility for single object output.
- Implemented tests to confirm zero rows are produced from empty arrays.
- Added validation tests to ensure array elements must be objects.
- Developed tests for one-to-many transformations with table suffix hints from VRL.

### Enhance Pipeline Transformation with Per-Row Table Suffixes
- **`src/pipeline/src/etl.rs`**: Updated `TransformedOutput` to include per-row table suffixes, allowing for more flexible routing of transformed data. Modified `PipelineExecOutput` and related methods to
handle the new structure.
- **`src/pipeline/src/etl/transform/transformer/greptime.rs`**: Enhanced `values_to_rows` to support per-row table suffix extraction and application.
- **`src/pipeline/tests/common.rs`** and **`src/pipeline/tests/pipeline.rs`**: Adjusted tests to validate the new per-row table suffix functionality, ensuring backward compatibility and correct behavior in
one-to-many transformations.
- **`src/servers/src/pipeline.rs`**: Modified `run_custom_pipeline` to process transformed outputs with per-row table suffixes, grouping rows by `(opt, table_name)` for insertion.

### Update VRL Processor Type Checks
- **File:** `vrl_processor.rs`
- **Changes:** Updated type checking logic to use `contains_object()` and `contains_array()` methods instead of `is_object()` and `is_array()`. This change ensures
compatibility with VRL type inference that may return multiple possible types.

* feat/allow-one-to-many-pipeline:
- **Enhance Error Handling**: Added new error types `ArrayElementMustBeObjectSnafu` and `TransformArrayElementSnafu` to improve error handling in `etl.rs` and `greptime.rs`.
- **Refactor Error Usage**: Moved error usage declarations in `transform_array_elements` and `values_to_rows` functions to the top of the file for better organization in `etl.rs` and `greptime.rs`.

* feat/allow-one-to-many-pipeline:
### Update `greptime.rs` to Enhance Error Handling
- **Error Handling**: Modified the `values_to_rows` function to handle invalid array elements based on the `skip_error` parameter. If `skip_error` is true, invalid elements are skipped; otherwise, an error is returned.
- **Testing**: Added unit tests in `greptime.rs` to verify the behavior of `values_to_rows` with different `skip_error` settings, ensuring correct processing of valid objects and appropriate error handling for invalid elements.

### Commit Summary
- **Enhance `TransformedOutput` Structure**: Refactored `TransformedOutput` to use a `HashMap` for grouping rows by `ContextOpt`, allowing for per-row configuration options. Updated methods in `PipelineExecOutput` to support the new structure (`src/pipeline/src/etl.rs`).
- **Add New Transformation Method**: Introduced `transform_array_elements_to_hashmap` to handle array inputs with per-row `ContextOpt` in `HashMap` format (`src/pipeline/src/etl.rs`).
- **Update Pipeline Execution**: Modified `run_custom_pipeline` to process `TransformedOutput` using the new `HashMap` structure, ensuring rows are grouped by `ContextOpt` and table name (`src/servers/src/pipeline.rs`).
- **Add Tests for New Structure**: Implemented tests to verify the functionality of the new `HashMap` structure in `TransformedOutput`, including scenarios for one-to-many mapping, single object input, and empty arrays (`src/pipeline/src/etl.rs`).

### Refactor `values_to_rows` to Return `HashMap` Grouped by `ContextOpt`
- **`etl.rs`**:
- Updated `values_to_rows` to return a `HashMap` grouped by `ContextOpt` instead of a vector.
- Adjusted logic to handle single object and array inputs, ensuring rows are grouped by their `ContextOpt`.
- Modified functions to extract rows from default `ContextOpt` and apply table suffixes accordingly.
- **`greptime.rs`**:
- Enhanced `values_to_rows` to handle errors gracefully with `skip_error` logic.
- Added logic to group rows by `ContextOpt` for array inputs.
- **Tests**:
- Updated existing tests to validate the new `HashMap` return structure.

### Refactor and Enhance Error Handling in ETL Pipeline
- **Refactored Functionality**:
- Replaced `transform_array_elements` with `transform_array_elements_by_ctx` in `etl.rs` to streamline transformation logic and improve error handling.
- Updated `values_to_rows` in `greptime.rs` to use `or_default` for cleaner code.
- **Enhanced Error Handling**:
- Introduced `unwrap_or_continue_if_err` macro in `etl.rs` to allow skipping errors based on pipeline context, improving robustness in data processing.
These changes enhance the maintainability and error resilience of the ETL pipeline.

- **Modify Function Signatures**: Updated function signatures in `etl.rs` and `greptime.rs` to use `RowWithTableSuffix` for better clarity and consistency.
- **Enhance Test Coverage**: Adjusted test logic in `greptime.rs` to align with the new `RowWithTableSuffix` type, ensuring correct grouping and processing of rows by TTL.
Files affected: `etl.rs`, `greptime.rs`.

perf(metric-engine): replace mur3 with fxhash for faster TSID generation
- Switches from mur3::Hasher128 to fxhash::FxHasher for TSID hashing
- Pre-computes label-name hash when no nulls are present, avoiding redundant work
