v0.3.0

Added

• Eager Loading Engine: Replaced complex lazy-loading stubs with a robust eager-loading orchestrator.
  Plugins are loaded in topological order, with package.path prepending for reliable module resolution.
• Pinning: Added pin = true field to plugin spec to permanently freeze a plugin at its current commit.
• Diagnostics: Added :Packard diagnose <name> command for interactive inspection of plugin state and module resolution.
• Startup Notifications: Added notifications option (enabled by default) to alert users if plugins are eligible for review on Neovim startup.
• Colorscheme Autoload: Automatically load cond-blocked colorscheme plugins when Neovim's ColorSchemePre fires (ADR-011).
• Hardening: Added force-push detection during update checks and improved build = false handling.
• UI Highlights: 29 custom highlight groups for full control over dashboard appearance.
• Help Tab: Added a sectioned help tab (?) with detailed keybinding documentation.
• Tests: Comprehensive e2e test for self-management and Windows compatibility.
• Documentation: Finalized vimdoc (:help packard) and beta-ready README.

Changed

• Shifted architecture from lazy-loading stubs to an eager-loading model to eliminate re-entry and mode-switching race conditions.
• Standardized user-facing messages via vim.notify().

Fixed

• Cross-platform path normalization for Windows compatibility.
• Self-protection logic for ruicsh/packard.nvim during orphan cleanup.
• Expansion popup border bleeding and highlight group documentation.
