Moves the [Unreleased] entries under ## [0.50.0] - 2026-09-11 and refreshes the compare links, [Unreleased] included.

Minor bump because the section carries an ### Added: the Commits tab naming the account each commit landed under (#582) and the README's Provider support table (#583).

One entry was in the section twice. "The window opens on Ubuntu instead of dying at launch." (#587) appeared a second time, byte for byte, further down the Fixed list; the second copy is dropped so the release page and the What's new dialog list it once.

No alert block: nothing in the section asks the reader to do or avoid anything, so this release opens no What's new dialog.

No other file moves: the version comes from the git tag, so nfpm.yaml is untouched.

Test plan

• grep '^## \[0.50.0\]' CHANGELOG.md matches once
• gofmt -l . clean, go vet ./... clean (vet run against a placeholder frontend/dist)
• go test -race ./... green
• cd frontend && biome ci . exit 0, vitest run green, tsc && vite build succeeds
• After merge: tag v0.50.0 on main so release.yml reads the ## [0.50.0] section
