chore(premiere-plugin): commit v1.0.0 installer artifacts

Drops dragonflight-premiere-panel-1.0.0-windows-setup.exe (2 MB) and
dragonflight-premiere-panel-1.0.0.zxp (35 KB) at
services/premiere-plugin/build/releases/v1.0.0/ so the binaries have
stable URLs on the forge without needing a separate release artifact
flow.

Heads-up: this commits 2 MB of binary into git history. Future bumps
should use Forgejo Releases (release assets are external to git history
and easy to delete) rather than another commit under releases/.

+
+## Artifacts
+
+| File | Size | Install path |
+|------|------|--------------|
+| [dragonflight-premiere-panel-1.0.0-windows-setup.exe](dragonflight-premiere-panel-1.0.0-windows-setup.exe) | 2.0 MB | Windows — double-click, Next → Finish |

+
+Bundle ID: `net.wilddragon.dragonflight.panel`. Replaces any prior
+`com.wilddragon.mam.panel` install (the `.exe` offers to remove it via a
+wizard checkbox; for the `.zxp`, delete the old folder manually).
+
+## Reproducing
+
+```
+cd services/premiere-plugin/build
+npm install
+powershell -File build-all.ps1
+```
+
+Requires Node 18+ and Inno Setup 6 (`winget install JRSoftware.InnoSetup`).
+See [`../README.md`](../../README.md) for the full build pipeline.
+
+## ZXP signing cert
+
+Signed with the self-signed cert at `../../cert/dragonflight-selfsigned.p12`
+(CN: `Wild Dragon LLC`, valid until 2051-05-17). Editors installing the
+`.zxp` must enable `PlayerDebugMode=1` once for CEP to accept the unsigned
+chain. The `.exe` installer handles this automatically for CSXS 8..13.
