v0.45.4

Changed

• Light theme colors adjusted for WCAG AA compliance (4.5:1 contrast ratio against white backgrounds)
• Replaced sharp with wasm-vips for image processing (resize, PNG conversion). Eliminates native build requirements that caused installation failures on some systems. (#696)

Added

• Extension example: summarize.ts for summarizing conversations using custom UI and an external model (#684 by @scutifer)
• Extension example: question.ts enhanced with custom UI for asking user questions (#693 by @ferologics)
• Extension example: plan-mode/ enhanced with explicit step tracking and progress widget (#694 by @ferologics)
• Extension example: questionnaire.ts for multi-question input with tab bar navigation (#695 by @ferologics)
• Experimental Vercel AI Gateway provider support: set AI_GATEWAY_API_KEY and use --provider vercel-ai-gateway. Token usage is currently reported incorrectly by Anthropic Messages compatible endpoint. (#689 by @timolins)

Fixed

• Fix API key resolution after model switches by using provider argument (#691 by @joshp123)
• Fixed z.ai thinking/reasoning: thinking toggle now correctly enables/disables thinking for z.ai models (#688)
• Fixed extension loading in compiled Bun binary: extensions with local file imports now work correctly. Updated @mariozechner/jiti to v2.6.5 which bundles babel for Bun binary compatibility. (#681)
• Fixed theme loading when installed via mise: use wrapper directory in release tarballs for compatibility with mise's strip_components=1 extraction. (#681)
