chore: release v0.2.0

[iuhoay]

Summary

Release v0.2.0. Bumps MARKETING_VERSION / CFBundleShortVersionString to 0.2.0 and moves the CHANGELOG [Unreleased] section into a dated [0.2.0] - 2026-06-15 entry.

This batches the work merged since v0.1.9 into a release: keyboard-first translation window, history/pin shortcuts, markdown-table rendering, auto-resize window, and the TTS markdown-stripping fix.

Changes

• mac-app/project.yml — MARKETING_VERSION and CFBundleShortVersionString → 0.2.0
• mac-app/Lumo/Info.plist — regenerated CFBundleShortVersionString → 0.2.0 (kept in sync with project.yml)
• CHANGELOG.md — [Unreleased] → [0.2.0] - 2026-06-15; added two entries that were missing from the section:
  • Added: auto-resize translation window (feat: auto-resize the translation window to fit the result #34)
  • Fixed: TTS no longer reads markdown markers/table pipes aloud (fix: strip markdown markers and table pipes from text-to-speech #31)

Release notes (v0.2.0)

Added

• Keyboard-first translation window: ⌘1 / ⌘2 / ⌘3 switch modes, ⌘R regenerates.
• ⌘Y opens history, ⌘P pins/unpins the window.
• Markdown tables render as a bordered grid instead of raw pipe-and-dash text.
• The translation window grows to fit the result (up to 85% of the screen), animating as it streams and settling to an exact fit.

Changed

• Action button relabelled "Run"; "Summarize" mode relabelled "Summary".
• Translate / polish / summarize preserve source structure (line breaks, lists, headings).

Fixed

• TTS no longer reads markdown markers and table pipes aloud.

Type of Change

• Release (version bump + changelog)

Notes for reviewers

After this merges to main, the release is cut by tagging the merged commit v0.2.0 and pushing the tag — the tag push triggers CI (release.yml) to build, EdDSA-sign, generate the appcast, and publish the GitHub Release.
