v0.0.5

feat: Release v0.0.5 - Plan Mode with runtime mode switching
@guilhermegouw guilhermegouw tagged this 12 Nov 09:46 
Major Features:
• Plan Mode - Read-only exploration mode inspired by Claude Code
• Runtime mode switching with Shift+Tab (Claude Code style)
• Persistent mode indicator at bottom of TUI
• Config support with environment variable override
• 21 comprehensive tests (100% passing)

Plan Mode:
• Restricts agent to 10 read-only tools (read, search, git status/diff/log)
• Prevents accidental file modifications during exploration
• Perfect for understanding codebases before making changes
• Toggle with Shift+Tab anytime during chat

Implementation:
• ExecutionMode enum (NORMAL, PLAN) with helper methods
• Tool registry filtering by risk level (SAFE tools only in Plan Mode)
• Agent integration with set_execution_mode() for runtime switching
• CLI flag: --plan to start in Plan Mode
• Config setting: default_execution_mode in settings.json
• Environment variable: CDD_EXECUTION_MODE=plan

UX Improvements:
• Custom markdown renderer with left-aligned headings (no underlines)
• Mode indicator always visible at bottom: "⏸ PLAN MODE (Read-Only)"
• Purple/gold color for Plan Mode, dimmed for Normal Mode
• Smooth toggling with Shift+Tab (no conflicts)

Testing:
• 21 unit and integration tests covering:
  - ExecutionMode enum functionality
  - Tool registry filtering
  - Agent mode switching
  - Config priority handling
  - End-to-end integration

Breaking Changes: None
Backward Compatible: Yes
