v0.13.0: Reactions, comment filters & Windows installer

What's new in v0.13.0 (#84)

Reactions

• Message reactions are captured and shown — as pills in the HTML export, and, with the new --reactions flag, inline in the TXT export (e.g. Nice post [👍5 ❤️2]).

Channel comments (--comments)

• Comment media is now downloaded and rendered too.
• Resumable: an interrupted run no longer re-scans every post on restart.
• The redundant channel post is no longer repeated inside every comment.
• HTML shows comments in a collapsible block per post with a "top N%" reaction filter (All / 1+ / Top 20% / 10% / 5%) that you can pin to the top while scrolling.
• New --comments-min-reactions N keeps only comments with at least N reactions.

Citations

• A reply to a message outside the downloaded date range now fetches the quoted message, so the citation is no longer empty.

Windows

• New installer: telegram-download-chat-v0.13.0-setup.exe — per-user install with Start Menu/desktop shortcuts and an uninstaller (no admin required).
• Self-update: Settings → Software Update → Update now downloads a tiny (~150 KB) app-*.zip and updates in place, instead of re-downloading the whole app.
• The single-file portable telegram-download-chat.exe is still available.

GUI

• Application version shown in the window title; greener, clearer progress bars.

Docs

• README now documents --split, --no-fast-download, --html, --html-media-links, and --pdf.
