fix(cli-registry): codex launch defaults as registry data, ultra footer, schema doc defaults

- Codex footer model detection (c28): the modelDetect.screenLine effort
  alternation is now built from CODEX_REASONING_EFFORTS plus 'default', so
  'ultra' (offered by the codexReasoningEffort App Setting and codex's own
  /model picker) is read and the launch enum and the footer reader cannot
  drift again. Still one capture group, 125 characters, no new quantifier.
  New session-display-model case loops every effort level, ultra included.

- No CLI-id branching for launch defaults (c27): the two mode === 'codex'
  branches the synced codex model/effort defaults added to the create and
  quick-start routes are replaced by a registry capability,
  capabilities.launchDefaults (launch param -> settings key, values from a
  closed enum), declared on the codex entry only. The resolver moved from
  web/codex-launch-defaults.ts to web/launch-defaults.ts as
  applyLaunchDefaults(mode, configs, customEndpoint), filling the entry's
  legacyConfigField object through legacyConfigAliases, still re-validating
  with SettingsUpdateSchema and never overwriting a caller's value. The
  route exclusions are unchanged (create: not remote; quick-start: not
  remote, not Docker, not a custom model endpoint), and quick-start still
  derives the session model from a bag without ompConfig, as before.
  schema.ts refuses an undeclared param, an unknown settings key, an empty
  map, and launchDefaults on an entry with no legacyConfigField.

- The no-id-branching guard now carries an exact occurrence count per
  allowlisted key, so a new copy of an already approved expression fails
  instead of riding the old approval, with a synthetic anti-vacuity case.

- SettingsUpdateSchema JSDoc (c21/c29): 'classic' is the tabArrangement
  default and 'compact' the headerStatsStyle default, matching the
  resolvers and the pre-paint script; state/case/ledger are marked opt-in.
