v6.15.0 release (#669)

**Related Issue(s):**

- None

**Description:**

- Added STAC_FASTAPI_ES_COERCE_GLOBAL env var to disable automatic type
conversion and enable strict type checking at the index level.

- Implemented CQL2 Abstract Syntax Tree (AST) structure for more
efficient query parsing and better support for datetime-based indexes.

- Made ES_MAX_URL_LENGTH configurable via environment variable to match
server-side http.max_initial_line_length settings.

- Replaced manual existence checks with native ES/OS op_type="create"
for faster bulk duplicate detection and better error handling.

- Atomic Redis queue operations using MULTI/EXEC pipelines to prevent
data inconsistency between ZSET and HASH.

- Added periodic lock refreshing to the item queue worker to prevent
distributed lock expiration during long batch processes.

- Fixed handling of empty collection_ids in query filters to prevent
invalid empty terms filters.

**PR Checklist:**

- [x] Code is formatted and linted (run `pre-commit run --all-files`)
- [x] Tests pass (run `make test`)
- [x] Documentation has been updated to reflect changes, if applicable
- [x] Changes are added to the changelog

 - Added coerce control via `STAC_FASTAPI_ES_COERCE_GLOBAL` env var to enable strict type checking by disabling automatic type conversion at the index level. [#649](https://github.com/stac-utils/stac-fastapi-elasticsearch-opensearch/pull/649)
 - Added CQL2 Abstract Syntax Tree (AST) structure for efficient query parsing and datetime-based indexes. [#659](https://github.com/stac-utils/stac-fastapi-elasticsearch-opensearch/pull/659)
 - Made `ES_MAX_URL_LENGTH` configurable via environment variable (default: `4096`). This value should match the `http.max_initial_line_length` setting in your Elasticsearch/OpenSearch server configuration. [#656](https://github.com/stac-utils/stac-fastapi-elasticsearch-opensearch/pull/656)
 
-### Changed
-
 ### Fixed
 
 - Fixed bulk duplicate detection: replaced manual `exist_ok` pre-check with ES/OS native `op_type="create"`. Bulk operations now correctly raise `ItemAlreadyExistsError` when `RAISE_ON_BULK_ERROR=true`, or count duplicates as "skipped" when `false`, instead of throwing raw `BulkIndexError`. [#638](https://github.com/stac-utils/stac-fastapi-elasticsearch-opensearch/issues/638)
 - Fixed `add_collections_to_body` to handle empty `collection_ids` gracefully, preventing an invalid empty `terms` filter from being added to the query body. [#656](https://github.com/stac-utils/stac-fastapi-elasticsearch-opensearch/pull/656)
 - Made Redis queue operations atomic using pipelines (MULTI/EXEC) in `queue_items`, `mark_items_processed`, `remove_item`, and `save_failed_items` to prevent ghost entries where IDs exist in ZSET but data is missing from HASH.
 - Added periodic lock refresh (every 60s) to `item_queue_worker` to prevent distributed lock expiration during long-running batch processing. The worker now stops processing when the lock is lost and checks `owned()` before releasing to avoid releasing another worker's lock.
