chore: upgrade to VS Code 1.106 / Electron 37 / Node 22 (#848)

Bump minimum VS Code from 1.95 to 1.106, upgrading the platform to
Electron 37 and Node 22. Update all dependencies, pin Electron to 37.7.0,
remove Node 20 workarounds, unify test runners under Electron, and add a
release pipeline safety check requiring tags on main.

 The coder client is vendored from coder/coder. Every now and then, we should be running `pnpm update coder`
 to make sure we're using up to date versions of the client.
 
+After running `pnpm update`, always run `pnpm dedupe` to consolidate duplicate
+package versions across the workspace. Without this, workspace packages can
+resolve to different versions of the same dependency, causing issues like broken
+React context propagation when two copies of a library are loaded.

 ## Releasing
 
+For both stable and pre-releases:
+
 1. Check that the changelog lists all the important changes.
 2. Update the package.json version and add a version heading to the changelog.
-3. Push a tag matching the new package.json version.
-4. Update the resulting draft release with the changelog contents.
-5. Publish the draft release.
-6. Download the `.vsix` file from the release and upload to both the [official VS Code Extension Marketplace](https://code.visualstudio.com/api/working-with-extensions/publishing-extension), and the [open-source VSX Registry](https://open-vsx.org/).
+
+### Stable Release
+
+1. Push a tag `v<version>` (e.g. `v1.15.0`) from the `main` branch. The release
+   pipeline will only run for tags on `main`.
+2. The pipeline builds, publishes to the VS Code Marketplace and Open VSX, and
+   creates a draft GitHub release.
+3. Update the draft release with the changelog contents and publish it.
+
+### Pre-Release
+
+1. Push a tag `v<version>-pre` (e.g. `v1.15.0-pre`) from any branch. The version
+   in the tag must match package.json (the `-pre` suffix is stripped during
+   validation). Pre-release tags are not restricted to `main`.
+2. The pipeline builds with `--pre-release`, publishes to both marketplaces, and
+   creates a draft pre-release on GitHub.
