misc 0.0.7

New helpers

intersect_filter_touch() — returns the rows of x whose geometries touch any feature in the mask y, using sf::st_intersects() only. No reprojection, clipping, or area computation is performed: geometries and attributes of x are returned unchanged. The lightest-touch selection strategy, condensed from the common st_intersects() |> lengths() |> { . == 1 } idiom.
clean_geo() — reads a .zip/.shp/.gpkg/.geojson, drops Z/M dimensions, replaces non-ASCII characters in attribute columns, reprojects to a target CRS (default EPSG:4326) and writes the result to a user-provided output path. The output format is determined by the extension of output and may differ from the input format. Replaces the standalone R/prepare_zip_shapefiles.R cleanup routine with a portable, testable function backed by zip::zip() instead of system("zip -j ...").

clean_geo() now normalizes the output path to an absolute path (via fs::path_abs()), matching the behavior already applied to path. Relative output paths (e.g. "data/clean/x.zip") previously failed when writing .zip output with zip::zip(); all output formats now resolve correctly against the current working directory.

view_vd() and view_vd_nonint() are explicitly macOS-only: on Windows or Linux they stop with a clear error. Documentation describes this platform restriction.
New terminal argument: "terminal" (Terminal.app, default), "iterm" (iTerm2), or "auto". For "auto", the choice comes from the MISC_VIEW_TERM environment variable and then from options(misc.view_term) ("terminal" or "iterm"); invalid values trigger a warning and fall back to Terminal.app.
AppleScript-based terminal launch is unified (new window or tab in iTerm2 as appropriate).
The vd (VisiData) executable must be on PATH before opening the viewer; the error message points to installation (for example pip install visidata).
If vdk is on PATH, the command used is vdk <project_basename> <file>; otherwise vd --default-width=500 <file>. In view_vd_nonint(), the project name uses basename(here::here()), consistent with view_vd().
view_mapview_from_path() performs the macOS check up front because the workflow relies on view_vd_nonint() for the attribute table; documentation updated.
