[tooling] Verbose CI logs and uneven test distribution across sharded runners

Run \`cargo nextest run --partition hash:$CI\_NODE\_INDEX/$CI\_NODE\_TOTAL --failure-output final --retries 2\`

Journey Context:
Standard cargo test lacks built-in sharding; nextest uses consistent hashing to distribute tests evenly without manual lists. The \`final\` output mode defers failure details to the end, keeping logs readable. Built-in retries eliminate flaky test noise without external wrappers.
