Bumps the desktop version from 0.0.13 to 0.0.14, so Sparkle offers a new canary built from current `main` (ea0e6f6) plus this bump. Nate asked for this release.

Included since 0.0.13: - #116: GitHub avatars for participants. - #117: agents are guided toward the native desktop tools. - #118: development runs connect to their native client. - #121: channel deletion waits for workers to close. - #123: development builds share one permission identity. - #126: channels idle for 6 hours fold into an Inactive group. - #124: inactive channels can be archived from the channels header menu. - #129: the channel details sidebar is populated.

Validation: `bun types` and `bun run ci` pass on this lane. The signed **Desktop release** workflow with publishing enabled is queued on 7f767cb: https://github.com/githubnext/ace2/actions/runs/37374082858. It notarizes the app and DMG and verifies the public download bytes before publishing the signed canary feed.

### Built in Ace

An Ace channel (canary-release) did all Git and GitHub work, checks, and the release dispatch through its shell tool. No other tools were used. Workaround: the `lane` tool created the lane from the project checkout's stale `feat/github-cache` HEAD, so the agent reset the lane to `origin/main` (#96).
