feat: add terminal image output utilities (Kitty + half-block truecolor)#10
Conversation
Add balsa::terminal module with three emission methods: - emit_kitty(): Kitty graphics protocol (Kitty/Ghostty/WezTerm) - emit_halfblock(): Unicode half-block chars with 24-bit ANSI truecolor - emit_auto(): auto-detect and pick the best method Includes base64 encoder for Kitty protocol payload and TERM_PROGRAM-based capability detection.
