…hared state)
A dock view *type* can resolve to a swappable iframe provider SPA:
- initHub({ viewProviders: { <type>: DevframeDefinition } }) mounts each
provider's SPA at <base><id>/ (serving its connection meta + statics) and
publishes <type> -> { base } to the read-only devframe:view-providers shared
state a UI reads to resolve the iframe URL (and to detect 'no provider').
- mountDevframe gains registerDock?: boolean; mountViewProvider(ctx, type, def)
is the reusable primitive (used by initHub, callable on the manual
createHubContext path). The headless core ships no provider — the reference
json-render provider comes from @devframes/json-render-ui.
- Keeps the in-process renderers seam untouched.
Adds VIEW_PROVIDERS_STATE_KEY + DevframeViewProviders types.

PR C of the json-render view-provider stack (plan:
plans/json-render-ui-packaging.md). Stacked on #185.Adds the generic mechanism that lets a dock view type resolve to a swappable iframe provider SPA — decoupling renderers from the hub UI's framework.
initHub({ viewProviders: { <type>: DevframeDefinition } })— mounts each provider's SPA at<base><id>/(serving its connection meta + statics) without a dock of its own, and publishes<type> → { base }to a read-onlydevframe:view-providersshared state a UI reads to resolve the iframe URL and to detect "no provider".mountViewProvider(ctx, type, def, { base })— the reusable primitive (used byinitHub; callable directly on the manualcreateHubContext+mountDevframepath).mountDevframegainsregisterDock?: boolean.@devframes/json-render-ui(jsonRenderProvider(), feat(json-render-ui): provider SPA (single-view + theming + provider factory) #185). The in-processrenderersseam is untouched (kept for custom in-process types).Adds
