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.
