Repin Parakeet Redux to the current upstream revision

moondream/parakeet-redux was rewritten upstream on 2026-09-23 to a single
commit (2bf128600aac), so the pinned revision fad622f no longer resolves.
model.safetensors still downloads from the old revision, but config.json,
ternary.json, tokenizer.json and README.md return HTTP 404, which makes
`install.sh --install-model` fail.

The weights, config, ternary map and tokenizer at 2bf1286 have the same
size and SHA-256 as the old pins, so the model itself is unchanged. Only
the model card README.md differs (8533 -> 8832 bytes), so its pin is
updated along with the revision.

Fixes #1
