v0.2.0 (3/N): extract Maker shared helpers (NameInput, Naming)

DRY pass identified by the post-v0.1.2 audit: every make:bridge:*
maker re-implemented the same "prompt, trim, ucfirst, reject empty"
closure in interact(), and the camel-case-to-separator regex was
duplicated between BridgeResourceMaker (`_`-joined route plurals)
and BridgeCommandMaker (`-`-joined kebab slugs).

Two helpers under PhpQml\Bridge\Maker\Support:
  - NameInput::askOrFail() — replaces 3× inline closures
  - Naming::camelTo($name, $separator) — replaces 2× inline regexes

All 3 makers now go through the helpers; behaviour preserved
(maker snapshot test still passes — generated Todo / TodoController
/ TodoList / MarkAllDoneController / TodoWindow byte-identical to
the v0.1.2 baselines).

NamingTest covers the documented cases plus a regression case for
acronyms (HTTPClient → h-t-t-p-client; the regex splits at every
internal capital, which is correct for the route-slug use case).

Test count 17 → 23, all passing.
