Follow up: audit hardening and CI

[silverbrit]

Summary

Follow-up work on top of feature/12.1-modernization. This adds the pending settings/package cleanup plus targeted audit fixes for custom aura trackers, anchors, Edit Mode, CI, native Better Tracked Bars settings integration, trinket defaults, and addon branding.

Settings and package refresh

• Added a persistent settings-window opacity control, retaining the 0.72 default while allowing a fully opaque window.
• Added a sidebar Changelog page with the single dated 33 (August 18 2026) release notes and updated the settings-window layout/navigation documentation.
• Simplified the in-game release notes to medium-detail technical summaries and added the Unhalted development credit and Discord feedback note.
• Added the missing PowerBar anchor-parent catalog and explicit UIParent (NONE) choices for bar positioning.
• Kept restricted Power Bar values in Blizzard's FontString formatting path instead of clearing them from Lua.
• Replaced the library XML aggregator with direct TOC library entries.
• Removed unused packaged media assets and updated install-deps.sh for the new dependency layout.
• Refreshed the README, CHANGELOG, and Options documentation to match the current addon architecture.

Custom tracker and anchor hardening

• Separated spell cooldown availability from aura-candidate availability. A valid spell ID that is not in the spellbook can now render through CustomAuraContainerTemplate without querying cooldown state as if it were a learned spell.
• Added regression coverage for aura-only spell metadata and unavailable non-aura sources.
• Added CanBeAccessedInContext() validation to shared imported-anchor checks.
• Routed Trinket Bar positioning through the shared safe anchor setter so forbidden, inaccessible, or throwing anchors fall back cleanly to UIParent.
• Added inaccessible-anchor regression coverage.
• Replaced the Edit Mode layout index's hardcoded preset offset with Blizzard's current preset-layout count, retaining a safe fallback.
• Shared Better Tracked Bars settings embedding between the standalone /bcdm window and native AddOns Settings, detaching the external canvas cleanly when either panel closes.

Trinket defaults and migrations

• Default the trinket viewer to show all equipped trinkets.
• Center the default trinket bar on Blizzard's UIParent, while retaining the ElvUI player-frame anchor when ElvUI is active.
• Migrate legacy ElvUI-anchored defaults idempotently and restore the contextual default on profile reset.

Addon metadata and minimap launcher

• Rename the visible addon and data-broker launcher to Better Cooldown Manager.
• Categorize the addon as Buffs & Debuffs.
• Style the minimap tooltip with white instructions and green action text.

CI

• Added a reusable Lua 5.1 test workflow for pushes and pull requests.
• The workflow checks Lua version, parses every tracked Lua file, and runs Scripts/test.lua.
• Release packaging now depends on the reusable quality workflow.

Commits

1. feat: refresh settings window and package layout
2. fix: support aura-only trackers and harden anchors
3. docs: simplify in-game changelog
4. fix: embed tracked bar settings in native options
5. fix: reset trinket defaults and migrate anchors
6. fix: update addon and minimap branding

Validation

• lua5.1 Scripts/test.lua .
• Lua 5.1 syntax checks with luac5.1 -p
• bash -n install-deps.sh
• git diff --check

Live WoW validation remains required for AuraContainer behavior, protected anchors, Edit Mode persistence, and combat/taint paths.
