Release v0.6.0 - Popup Architecture & Help Panel Upgrade

🚀 BlockChainInfo v0.6.0 – Popup Architecture & Help Panel Upgrade

This release marks one of the most important steps toward v1.0.0 —
the transition from a single hard-coded popup to a scalable, enum-driven popup system, plus the addition of a fully polished Help Panel accessible everywhere in the dashboard.

This brings BlockChainInfo into a more mature, unified, and future-proof architecture.

⭐ What's New

1. Popup System Refactor (Enum-Based)

• Replaced the old show_popup: bool with a new PopupType enum.
• Enables multiple popups (Tx Lookup, Help, future settings panels).
• ESC now universally closes any popup.
• Cleaner, modular, and significantly more maintainable.

Popup states now include:

• None
• TxLookup
• Help
  (Future additions require zero refactoring.)

---

2. New Help Panel (? Key)

• Open Help panel using ?, the universal TUI help key.
• Displays global controls, section descriptions, and app structure.
• Mirrors the Tx popup styling for a unified UI experience.
• Clean, centered, color-consistent, and version-ready.

---

3. Unified Popup Styling

All popups now use a consistent theme:

• Yellow border + title
• Green informational text
• Cyan for user input (Tx Lookup)

This brings the entire interface into a cohesive style, preparing for 1.0.0 polish.

---

4. Refined Input Handling

Tx Lookup input logic migrated cleanly to the enum system:

• Character typing gated only when popup == TxLookup
• Paste detection logic preserved
• Backspace + Enter behavior identical and intact
• ESC resets paste state and closes popups

Zero regressions.
Perfect isolation between popups.

🛠️ Improvements

• Simplified event handling pathways
• Reduced clutter in runapp.rs
• Increased clarity in popup activation logic
• Code is now easier to extend and reason about

This release lays the final architectural groundwork for future panels like:

• Settings
• Network Node Summary
• Difficulty Epoch Info
• About / Version Info

🔮 Next Steps Toward v1.0.0

• Final pass on toggle consistency
• Light code cleanup / minor refinements
• Help panel content review
• README update
• Final polish before tagging v1.0.0

🧩 Version Bump

0.5.1 → 0.6.0

Rationale:

• Adds new features (Help panel)
• Introduces an architectural upgrade (enum popup system)
• Does not introduce breaking changes
• Significant step toward v1.0.0
