ggpsychro 0.1.0

• Made the Givoni-Milne strategy overlay default to the fixed 1979 comfort anchor, clarified comfort API documentation, and switched psychrometric polygon theme elements to ggplot2::element_polygon().
• Refined comfort overlay APIs and documentation, added Givoni-Milne strategy variants with custom comfort anchors, and added CI-only ggplot2 compatibility checks, plus CRAN preflight metadata cleanup. (#37)
• Cleaned up internal helper naming across package modules and split large comfort and chart test files into focused test suites. (#36)
• Streamlined comfort, grid, coordinate, and stat internals; renamed the PMV comfort and psychrometric grid APIs; and removed the package-local RStudio project file. (#35)
• Replaced external path-label rendering with a native textpath renderer for psychrometric grid labels and comfort overlay labels. (#34)
• Addressed CRAN preflight checks by adding return-value documentation and recording the copyright-holder role. (#33)
• Refactored the ggpsychro build pipeline and comfort overlay internals to isolate build-time state, guard ggplot2 internals, and split comfort code into focused modules. (#31)
• Added runnable reference examples across exported documentation topics and grouped pkgdown reference pages by workflow area. (#29)
• Preserved ordinary ggplot2 aesthetics across legacy psychrometric stats. (#27)
• Replaced foreground psychrometric panel masking with valid-region clipping for ggpsychro-generated grids, stats, tiles, zones, and comfort overlays, while allowing ordinary ggplot layers to draw in the mask area and state markers to render above the saturation boundary. (#4, #28)
• Added Heat Index overlays, Givoni bioclimatic strategy zones, and per-zone styling controls for Givoni overlays. (#24)
• Added optional inline contour labels to comfort overlays. (#26)
• Clarified SET and adaptive comfort overlay examples in the comfort overlays article. (#25)
• Added README acknowledgements for external psychrometric-chart references and refined SET/adaptive comfort overlay examples. (#23)
• Added README and pkgdown documentation for comfort overlays and the psychrometric protractor. (#22)
• Added an ASHRAE-style psychrometric protractor for sensible heat ratio and heat-moisture-ratio guides, including Mollier rotation support, overall scaling, and independent mask-area margins. (#21)
• Added thermal comfort calculations and comfort overlay layers for PMV/PPD, SET, adaptive comfort, PMV contours, PMV-based ASHRAE 55 / EN 15251 comfort zones, and point-state comfort metrics. (#20)
• Removed an ambiguous specvol-rh zone example from the reference documentation. (#19)
• Clipped geom_psychro_tile() bodies to the saturation curve so tiles stay inside the valid psychrometric region. (#17)
• Added runnable core reference examples for psychrometric stats, grid helpers, state/process layers, zones, and explicit coordinates. (#18)
• Added website-only pkgdown articles and shortened the README. (#15)
• Added psychrometric tile bins. (#14)
• Added psychrometric chart presets. (#12)
• Added psychrometric zones and process layers. (#13)
• Rendered psychrometric grid labels. (#11)
• Revived the dual psychrometric grid API. (#10)
