test: fix prometheus-prompt syntax + sync display name casing to lowercase

- prometheus-prompt.test.ts: close missing }) on the OpenSpec expanded
  commands describe block (introduced by d66b6bcbf, parse error).
- agent-sort-shim/agent-config-integration/continuation-injection/
  unstable-agent-babysitter/subagent-resolver/sync-executor/
  resolve-caller-team-lead tests: expect 'Sisyphus - ultraworker'
  (lowercase) to match production after cd39f8858, which lowercased the
  display name to dodge a TUI ZWSP rendering glitch. Legacy uppercase
  inputs that exercise the normalization path are preserved.
- sync-executor.ts + resolve-caller-team-lead.ts: route legacy display
  name inputs through normalizeAgentForPrompt so prompt agent names and
  caller team lead lookups produce the canonical lowercase form.
