Summary

Documents two Pro deduplication behaviors surfaced during review, and adds the missing Global Vulnerability ID algorithm entry to the tuning guide:

  • Two tools on the same instance-wide algorithm become mutual dedup candidates. When two different tools are both configured with Global Component (or Global Vulnerability ID), they share a constant grouping hash and are considered for deduplication against each other on that shared dimension — intended cross-tool behavior, now documented.
  • Feature flags do not gate an existing configuration. A tool's saved Deduplication Settings stay in effect regardless of feature-flag state; disabling a flag does not retroactively revert dedup. To change behavior, update the tool's Deduplication Settings (which queues the background re-hash).

Docs-only change to PRO__deduplication_tuning.md.

…ence behavior

Two behaviors surfaced in review of the Pro dedup work:
- Two different tools set to the same instance-wide algorithm (Global Component
  or Global Vulnerability ID) share a constant grouping hash and become mutual
  deduplication candidates (F23) — document as intended cross-tool behavior, and
  add the missing Global Vulnerability ID algorithm entry.
- A tool's saved Deduplication Settings stay in effect regardless of feature-flag
  state; disabling a flag does not retroactively revert dedup (F20).
