🧰Neo Angband: ModForge v1.0.0

Added

• A launch screen, an exit screen, and an in-app README (neo-angband#126). Entering ModForge previously dropped straight into the workshop’s mod list with no transition, and exiting simply closed the shell with no acknowledgement. Both now get a native HTML5 screen - shadow-DOM overlays matching the pattern already used elsewhere in the shell - and the exit screen’s README summary is reachable without leaving the tool.
• A sections seam (neo-angband#47). A record file’s sections block reached the emitted folder exactly as written, but the draft model had no way to represent a section: the composer never saw it, and the review screen’s verdict did not cover it. A section now gets a manifest entry and its content is grouped under it, so the composer and review screen model it the same way they model other content types. Additive SDK work with no change to the plugin ABI.
