Release under the SolidCraft name: binaries, assets and installers (#383)

* Release under the SolidCraft name: binaries, assets and installers The desktop binary is now `solidcraft` and the CLI `solidcraft-cli` (the two app packages are renamed; their folders move with the rest of the rename later). Every release asset is named solidcraft-<ver>-… / SolidCraft-<ver>-windows-x64.exe, and the installers show the SolidCraft product name. Kept so existing installs keep updating (docs/compatibility.md): - `solvecraft-cli` alias binary in every package, forwarding to solidcraft-cli with a deprecation note on stderr (tests/legacy_alias.rs). - Linux app ID ai.storyteller.solvecraft (Flatpak ID, desktop entry, Wayland app_id). - MSI UpgradeCode, so the MSI upgrades in place. - deb Replaces/Conflicts/Provides and rpm Obsoletes/Provides solvecraft. - An old-named .zsync copy so earlier AppImages find updates; a legacy .flatpakrepo copy. - .solvecraft file associations; SOLVECRAFT_* fallbacks in the packaging scripts.

+package; the Flatpak app ID `ai.storyteller.solvecraft` is unchanged, so Flatpak updates

 .SYNOPSIS
-  Build and package SolveCraft for Windows.
+  Build and package SolidCraft for Windows.

 .DESCRIPTION
  Produces, in $env:DIST (default: dist/release):
-    solvecraft-<version>-windows-<arch>.msi            per-machine installer (WiX v5)
-    solvecraft-<version>-windows-<arch>-portable.zip   solvecraft.exe + solvecraft-cli.exe + licences
-    SolveCraft-<version>-windows-<arch>.exe            the app alone (x64 only: a plain download)
+    solidcraft-<version>-windows-<arch>.msi            per-machine installer (WiX v5)
+    solidcraft-<version>-windows-<arch>-portable.zip   solidcraft.exe + solidcraft-cli.exe + licences
+                                                       (+ the solvecraft-cli.exe compatibility alias)
+    SolidCraft-<version>-windows-<arch>.exe            the app alone (x64 only: a plain download)

  The binaries link the C runtime statically (+crt-static), so nothing else needs installing.
-  The icon comes from $env:SOLVECRAFT_ICONS (solvecraft.ico, made by `solvecraft-cli icon`), or
+  The icon comes from $env:SOLIDCRAFT_ICONS (solidcraft.ico, made by `solidcraft-cli icon`), or
  is drawn by the CLI just built when this machine can run it. Nothing is signed.

  Needs: Rust (MSVC toolchain + the target) and WiX v5:
