v0.20.0 - Confluence Page Title From Markdown H1

Added

• confluence_update now sets the Confluence page's title from the source
  markdown's first H1 heading, falling back to the existing (GET-fetched)
  title unchanged when no H1 is present (GitHub issue #76).

Fixed

• specmgr://config now reports the sysrs domain (it was missing from
  the resource's domains dict even though sysrs was already fully
  wired into every dispatch tool), matching every other domain's entry
  (GitHub issue #74).
• Corrected stale/incorrect copyright holders in NOTICE for pydantic,
  python-dotenv, typer, rich, and mcp; added missing attributions
  for mdformat, mdformat-simple-breaks, and httpx (GitHub issue #73).
