chore(release): prepare 0.50.0

[elkaix]

Bump 0.49.0 → 0.50.0: staged-update fix (no mid-session onefile corruption) + update notice below input. 8-file mechanical release bump; all local + CI gates green.

Changes

• pyproject.toml / uv.lock: version 0.49.0 → 0.50.0
• CHANGELOG.md / docs/en/release-notes/changelog.md: Unreleased → 0.50.0 (2026-06-20)
• docs/en/release-notes/breaking-changes.md: 0.50.0 entry (no breaking changes)
• README.md: What's New 0.50.0, all version references bumped
• docs/en/guides/getting-started.md / packages/linux-installer/README.md: version references bumped

Gate results
