Add Hellion fork README, NOTICE, and COPYRIGHT

Initial Hellion Forge documentation for the Craftimizer fork.

- Replace stub README with full project page (badges, fork scope table,
  tech stack, build instructions, project status, license block, FFXIV
  disclaimer, Hellion Forge footer)
- Add NOTICE.md with acknowledgement to Asriel Camora as the upstream
  author, direct word on fork intent, scope of changes, contact path,
  and explicit non-upstreaming rationale
- Add COPYRIGHT with dual-holder source code block (Asriel 2023 +
  Hellion Online Media 2026 for the SDK 15 maintenance), visual asset
  block (Hellion Forge logo by Florian Eck, all-rights-reserved), and
  bundled binary attribution (Raphael solver)
- Drop in the Hellion Forge logo under docs/images/

LICENSE remains unchanged — Asriel Camora's original MIT notice is
mandatory under MIT clause 3.

+# Notice
+
+## Acknowledgements
+
+This Craftimizer fork is built on
+[Craftimizer](https://github.com/WorkingRobot/Craftimizer) by
+**[Asriel Camora](https://github.com/WorkingRobot)**, who built and
+maintained the plugin for years. The entire architecture, the crafting
+simulator, the macro solver, the recipe data layer, the synthesis helper,
+and every UI window come from Asriel's work. Without Craftimizer, this
+fork would not exist.
+
+If this fork is useful to you, the credit for that belongs in large
+part to Asriel.
+
+## A direct word to Asriel
+
+Hi. I am Jon. I forked Craftimizer because the upstream `main` branch
+had not received an update past FFXIV 7.4, and I wanted a working
+crafting plugin for personal use that still loads on the current Dalamud
+API. This is not a "do it better" fork. The opposite is true. I would
+have happily kept using upstream if it had stayed current.
+
+What this fork adds is purely a Dalamud SDK 14 → 15 migration cycle.
+Concretely, three changes in `FFXIVClientStructs` and Dalamud's `ImRaii`
+namespace were renamed or removed; this fork ports the affected call
+sites to the new symbol names and adds a local `IEndObject` interface to
+replace the nested one Dalamud removed. No new features, no design
+departures, no rebranding of internal namespaces. Where I had to modify
+your sources I kept the edits minimal, isolated to the lines the SDK 15
+compiler refused, and revertible.
+
+If you pick Craftimizer back up and ship an upstream SDK 15 update, this
+fork folds back into a pure mirror and the recommendation will be to
+switch back to your build.
+
+If anything in this fork ever steps on something you would not be okay
+with — attribution, naming, anything else — please reach out and I will
+fix it. Genuinely.
+
+## Why this fork exists
+
+The upstream `main` last commit is "Update for 7.4" from late 2025. The
+plugin is otherwise dormant: no SDK 15 branch, no public roadmap, no
+recent issue activity from the maintainer. FFXIV 7.5 brought the Dalamud
+API jump from level 14 to 15 in early 2026, and Craftimizer stopped
+loading from then on. My personal crafting workflow depends on it, so I
+took the maintenance burden on for a while.
+
+This fork is maintained for personal and friend-circle use under Hellion
+Forge. It is not a competing project and does not target the broader
+Craftimizer user base.
+
+## Why this fork is not upstreamed
+
+I did not open a pull request because the upstream repository has been
+quiet for months and there is no signal that maintenance bandwidth is
+available on Asriel's side. A drive-by SDK-15-bump PR with no maintainer
+to land it would sit open indefinitely and create the wrong impression
+that the change has been reviewed. If upstream becomes active again and
+wants the migration, the change set is small enough (+23 / -19 lines,
+seven files) to merge by hand in minutes.

+I respond on weekdays during European business hours. For attribution
+or takedown questions, email is the fastest path.
+
+## Trademarks and naming
+
+"Craftimizer" is the name Asriel chose for the upstream plugin. This
+fork keeps the name as a reference to the origin and does not rebrand
+the user-facing identity. The Hellion brand is mine.
