## Description
Created `Release Test Workflow` that for now executes load tests. It's
being triggered manually and on a PR to `main`.
NOTE: Release workflow is not in required checks because it contains new
and unstable tests. We will need to watch it ourselves.
The `Load Test` workflow is being called from the `Release Test
Workflow` and also manually on demand.
Limited load test duration to 60 minutes.

- Implements `TextChunkerWithOverlap` with configurable
`chunk_overlap_ratio`
- Abstracts chunk_data generation via `get_chunk_data` callable
(defaults to `chunk_by_paragraph`)

(0% overlap) produce identical output for all edge cases.
