agentbuffs 0.5.0

Changed

• "Show the changes first" and --dry-run print the full text of the skill file, not only its size and checksum. The skill holds instructions your agent follows, so you can now read them before you approve.
• The skill preview shows control characters and invisible characters, such as escape codes and zero-width marks, as <U+XXXX> codes. The file is still written exactly as downloaded.
