v0.6.1

Features

• sdt update now shows an interactive download progress bar when running in a terminal, and reports the downloaded size on completion.
• README now includes an animated demo of grading and rewinding.

Fixes

• macOS launchd background grading now runs with a real PATH, matching foreground grading behavior and avoiding “command not found” failures.

Improvements

• Ignore handling is now consistently based on .sdtignore and always ignores .sdt (and .git when present); removed remaining .grignore/legacy ignore merging.
• UI now tracks whether output is a TTY separately from color support, enabling cleaner terminal rendering decisions.

Breaking Changes

• Removed support for legacy .gr repositories and associated discovery paths; existing repos must be .sdt.
• Removed legacy config directory fallback (gr) and legacy environment variable spellings (e.g. GR_AUTHOR, GR_PROMPT, GR_AGENT).
• Sealing manifest file name changed to .sdtsealed (from .grsealed); existing sealed repos may require migration.
