Relock onto sigil 0.20 and drop the caret sigil: field

Message

courier's CI failure was NOT a stale worker cache, which is what t-4182b8 and then t-e71594 claimed. It was this repo's own lock being behind the runner.

Measured after the golden image was rebaked onto sigil 0.21.0:

courier, declaring sigil: "^0.19" and never relocked, failed run 237 with 6 LOAD ERROR / invalid native function index -- byte-identical counts to run 204 on the OLD image.
sigil-wise, declaring sigil: "0.20" and relocked today, PASSED on the same new image in the same window.

So the runtime moved forward and this repo's pinned artifacts did not. invalid native function index is a native-function-table mismatch, and it points at whichever side is behind -- which was never the worker.

The mechanism findings in t-e71594 still hold: runners are 196 KiB overlays over a read-only golden image, discarded per lease, so the baked deps genuinely cannot be purged. What was wrong was the CONCLUSION drawn from them, that a re-bake was the only possible fix. The re-bake moved the runtime further from this repo's pins and the failure reproduced exactly.

The sigil: field also carried the caret spelling deprecated since 2026-08-25; it declares a MINIMUM, not a range. Suite: 120 passed from a clean tree.
