docs: add Tag Filtering feature to guide and reference ContinuousCompliance strategy

[Copilot]

Pull Request

Description

Addresses two documentation gaps: Tag Filtering was missing from the guide's Key Features summary (present in README but not guide.md), and neither doc referenced the Continuous Compliance strategy that ReqStream is a component of.

Changes

• README.md — Added 🔒 Continuous Compliance as a feature bullet in the Features list (using [link-continuous-compliance] ref); removed inline Overview sentence
• docs/guide/guide.md — Added Tag Filtering to the Key Features list; replaced inline Use Cases mention with a dedicated # Continuous Compliance section containing a ## Key Practices subsection; added <!-- Link References --> comment before the link section

The ContinuousCompliance placement and structure aligns with the pattern established in TemplateDotNetTool PR #53.
