release: v1.2.26 (#51)

* chore: release v1.2.22

- DRY: consolidates edition regex (filters/post_processor) and tag
  extraction (qbittorrent/queue_manager) to eliminate duplication
- Fix: _format_result_details CRAP score reduced (CC 10→8)
- Fix: resolution_label_from_height now recognizes 4320p as UHD
- Refactor: HttpClient context manager protocol + updated User-Agent
- Chore: _group_is_rejected efficiency (O(n) → O(1))
- Chore: mypy type fix for _dispatch_apprise body_format

* fix: replace html.escape with _escape_markdown_text in _format_result_details

html.escape() produces HTML entities (e.g. ') which appear literally
in ntfy notifications since the body is sent as Markdown.  Switched to
_escape_markdown_text() for Markdown-compatible escaping.

Closes: ntfy notification formatting showing raw HTML codes

* feat: auto-append ?format=markdown to ntfy Apprise URLs

Ntfy's Apprise plugin defaults to TEXT format unless the URL carries
a ?format=markdown parameter, causing Markdown formatting to render
literally.  Automatically append the parameter to ntfy:// and
ntfys:// URLs at dispatch time so users get proper Markdown rendering
without manual configuration.

* improve ntfy format

* docs: spec for notification body formatting visual polish

* docs: implementation plan for notification body formatting visual polish

* chore: bump version to 1.2.26
