feat(ci): OS/OS_VERSION manual dropdowns + restore lost crow fix #97
2026-06-18
fix(ci): derive build-all platform/arch in-container, not from CI env
Crow cannot interpolate the workflow-level OS/OS_VERSION form variables inside an environment: block (only matrix variables work there), so exporting them broke pipeline parsing with "unable to parse variable name". Instead, derive platform + arch inside build-all.R from the running container, mirroring bincraft's own codename -> platform mapping and machine -> arch detection. This keeps the already-built dedup pre-filter effective without depending on CI-injected env vars, and degrades to a length-1 NA (querying nothing) for an unmapped codename rather than crashing.
feat(ci): make OS and OS_VERSION manual-run dropdowns
Give the OS and OS_VERSION form variables explicit option lists like target_arch and R_VERSION already have, so the manual-run form presents dropdowns instead of free-text. Crow form variables are independent, so the operator must still pick a coherent OS + OS_VERSION combination.
