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.

 - **`PublisherInterface`, `ModelPublisherInterface`, `CorrelationContextInterface`.** The bridge's three public services now ship as interfaces (same namespace as concrete, mirroring upstream `HubInterface`/`Hub`). App controllers and listeners should typehint these instead of the concrete classes so swappable implementations (offline-buffer publisher, request-stamp correlation context, etc.) remain non-breaking. Existing `Publisher` / `ModelPublisher` / `CorrelationContext` classes implement the new interfaces unchanged.
 - **`BridgeOp` enum.** PHP 8.1 string-backed enum (`Upsert` / `Delete` / `Replace` / `Event`) replacing the raw `'upsert'`/`'delete'` strings previously passed between `DoctrineBridgeListener` and `ModelPublisher::publishEntityChange`. Values match PLAN.md §4's envelope `op` wire format. Typo'd ops are now caught at the type level instead of silently producing envelopes clients ignore.
 - **`BridgeBundleInfo` value object** carrying the bundle's name + class FQCN. `HealthController` now constructor-injects this instead of `PublisherInterface` as the deep-load canary, so the readiness probe is no longer coupled to the publisher's contract. `/healthz` response gains a `name` field (`php-qml/bridge`); the `bundle` field now reports `PhpQml\Bridge\BridgeBundle` (was `PhpQml\Bridge\Publisher`).
+- **`Maker\Support\NameInput`** — shared interactive name prompt. All three `make:bridge:*` makers (`resource`, `command`, `window`) re-implemented the same "prompt, trim, ucfirst, reject empty" closure inline; collapsed into one call site so empty-argument and validation behaviour stay in lockstep.
+- **`Maker\Support\Naming`** — `camelTo($name, $separator)` helper. Replaces inline `preg_replace('/(?<!^)[A-Z]/', $sep.'$0', $name)` regex copies (BridgeResourceMaker emits `_`-joined route plurals, BridgeCommandMaker emits `-`-joined kebab slugs).
