Add MB-61508 — issue with unnecessary index intersect scans

Add new REST API options and cluster identification updates

This commit introduces several new settings to the `/pools/default/buckets` REST API.

Improve warmup behavior configuration in Couchbase Server

Replaced `warmup_min_memory_threshold` and `warmup_min_items_threshold` parameters with a unified `warmup_behavior` setting. The new parameter offers three modes: `blocking`, `background`, and `none`, providing more flexibility and faster bucket availability.

Update headings and details in release notes and feature docs

Revised section titles to align with terminologies ("Data Service" and "Query Service") and improved clarity of information in release notes and new features for version 8.0.0. Added explanation for warmup behavior enhancements in the Data Service.

*Note: The AsciiDoc for MB-9418 is a tad fragile, as it uses the open block to format the list. This should probably be replaced when AsciiDoc is updated to use the new open block syntax (~~~~).

Release note addition: Enhance HashTable resizing to reduce vBucket latency

Enhance resiliency of Eventing Service during disruptions documented for release note.

Add backup retention configuration feature to release notes

Introduced the ability to configure a retention period for backups in the Backup Service.

Fix incorrect value range formatting in release notes

Corrected the display of value ranges for `kv_ep_mem_low_wat_percent_ratio` and `kv_ep_mem_high_wat_percent_ratio` to use consistent formatting (0–1). This ensures the release notes convey accurate and clear information.

Update release notes and new feature sections for 8.0.0

Added details about fixed issues in the Storage section and new Data Service metrics in the release documentation. Also aligned section headers for consistency and introduced clarifications on new features like XDCR, Query Engine, and Vector Search.

Format the `--disable-safe-remove-check` flag.

Enhance release notes and new features documentation.

Added details about XDCR CAS guardrails, improved backup safety checks, and new Index Service replication enhancements. Updated tools section with changes to job concurrency prevention and backup plan modifications.

Update release notes with XDCR and Query Service fixes

Added details for multiple XDCR fixes, such as resolving deadlocks, handling negative replication state values, and improving JSON validation for advanced filtering. Updated Query Service fixes, including corrections for legacy `LOOK UP JOIN` handling and precision issues with large integers.

Updating the `new features` and `release notes` for the version 8.0.0 release.
