Merge current master into PR #219 fixes

Origin/master advanced after the reviewed fixes were first pushed, leaving PR #219 conflicted. Merge the new vendor Cordis/loader update into the PR branch rather than rewriting pushed history, so the task fixes remain based on the exact current landing target.

Preserve the upstream package graph, lockfile, app-boot, and built-bin adjustments as landed on master; resolve only genuine overlaps with the task fixes and regenerate derived artifacts where required.
