v0.6.0: Permission guide, AI Node color tinting, tmux session detection improvements

[cnshsliu]

VoiceVibeCode v0.6.0 is out. Two sessions of work landed today — here's what shipped.

Permission onboarding. New 3-step permission guide walks users through Accessibility → Input Monitoring → Microphone with polling, skip timer, and proper window activation. The guide window shows in Dock and CMD+TAB during the flow so users don't lose it behind other windows. Also removed Documents and .cache fallback paths from WhisperKit model scanning — those triggered unnecessary macOS privacy prompts.

AI Node animation tinting. The spinning arcs and center dot in the processing indicator used neutral gray/white — bright enough to be distracting on dark backgrounds. They now follow the active state color: blue during Whisper recognition, green during LLM post-processing. The tinting is brightness-layered — center dot at 1.5×, inner arc at 1.2×, outer arc at 0.9× of the base color — so the visual hierarchy is preserved without the harsh white.

Claude Code session detection. ClaudeSessionWatcher got a significant rewrite for tmux context extraction. Better client activity sorting, explicit pane targeting with -t <pane>, and support for more terminal emulators (WezTerm, Kitty, Ghostty) alongside the existing iTerm2 support.

Also: Updated app icon, localization infrastructure for future i18n, and entitlements/codesign fixes for distribution.
