Stabilize local dev merge

Align regression tests with the current Odysseus behavior after merging origin/dev into local main.

- keep phone/name-only contacts valid and cover null email without crashes

- pin explicit web-search false form submission in chat.js

- update Cookbook dependency/download completion tests for combined live + persisted output

- expose SGLang OS package repair hints from backend diagnosis

- treat MLX and MLX-community repos as servable on Apple Metal while keeping CUDA behavior unchanged

- keep desktop new-chat coverage on the shared preferred-model helper

- remove a hardcoded crop overlay portal z-index literal

- include the local agent-loop cleanup that removes the old manage_notes reminder repair shim

Verified with: docker run --rm -v /home/pewds/odysseus-cookbook-fresh:/app -w /app odysseus-cookbook-fresh-odysseus python3 -m pytest -q (4515 passed, 4 skipped).
