Changelog draft

[2.9.0] - 2026-09-04

Added

• In-table add: Trailing dotted + Add character column and + Add raid row on the main tracker table open the existing add forms (toolbar buttons unchanged). Empty raid list shows a template hint under the add-raid control.

Fixed

• Add raid sticky: The + Add raid cell stays pinned with the left dungeon columns while character columns scroll horizontally.
• Healer gear hints: Reign of the Unliving / Reign of the Dead (N/H) are no longer suggested as ilvl upgrades for healer specs (resto, holy, disc).

Changed

• Docs: README EN+RU mention the dotted in-table add affordances.
