Move verbose into Config; drop resolveVerbose

Verbose was awkwardly a separate runKeeper argument with a separate
resolveVerbose helper, even though it's just another tunable on the
same precedence ladder as the numeric fields. This commit collapses it.

Changes:

- Config gains 'readonly verbose: boolean'. DEFAULT_CONFIG sets it to
  false.
- resolveConfig now returns the full Config including verbose. Verbose
  layers with the same 'first defined value wins' precedence as the
  numeric fields.
- resolveVerbose is gone.
- ParsedCliArgs.verbose becomes boolean | undefined: undefined when -V
  was not passed, true when it was. parseCliArgs maps accordingly.
  This lets the layered resolver treat verbose uniformly.
- runKeeper takes a single Config arg. The internal logger reads from
  config.verbose at the top of runKeeper.
- move.ts no longer plumbs verbose separately; the single resolved
  Config drives everything.
- README How-it-works and Files-table entries updated to match.

Behavior verified for all five verbose-precedence cases (no file/no
flag, no file/-V, file:true/no flag, file:false/-V, file:false/no
flag) and config-error scenarios remain intact.
