v0.7.0: UX improvements for first-time users

New Features

• lpr_check() / checkPackRat(): diagnostic function that validates project state, checks file integrity, and reports optional dependency status
• lpr_* aliases for all 12 exported functions (e.g., lpr_init, lpr_export, lpr_query_ot) — easier tab-completion and discoverability; both CamelCase and lpr_* names work identically
• New vignette: new_ux_features demonstrating check and alias usage

Improvements

• Moved plotgardener and httr from Imports to Suggests with requireNamespace() guards, reducing the install footprint for users who don't need locus zoom plots or MouseMine queries
• buildPacket() zip creation now tries the zip R package first, then falls back to system zip, with an informative error if neither is available
• Expanded README with install instructions for all 4 genome builds (hg38, hg19, mm39, mm10) and lpr_* quick-start examples

Internal

• Consolidated duplicate helpers (.render_genes, .standardize_chrom) and %||% operator into single definitions
• Added zip to Suggests
