feat(web): in-app workspace-directory browser as the shipped picking default

The Open-local-folder flow now branches on the Host's advertised picker
interaction (host.describe.directoryPicker, read per menu open; unknown
kinds hide the entry): dialog keeps the native-chooser flow, and browse
opens the new in-app directory browser (figma Harness 802-56979) —
breadcrumbs rooted at a localized Home crumb, a click-to-edit path zone
right of the crumbs, host-flagged hidden entries filtered client-side,
an inline New-folder row, and Open adopting the listed directory
through the existing workspace-creation error surface. Dialog copy is
localized (ctx.locale, namespace 'workspace'); the plugin re-registers
its entries on locale/change.

apps/cli flips the composed backend from -dialog to -browse, so the
picker works for remote deployments out of the box; -dialog stays a
composable alternative. The workspace-management e2e drops its native
picker monkey-patch and drives the real modal end-to-end via the
path-edit affordance.

+- `cordis.yml` chooses the interaction; `apps/cli` mounts `-browse` (the in-app browser is the shipped default), the GUI branches on `describe`, and `-dialog` stays a composable alternative for host-display deployments.
 - The wire gains `host.listDirectory`/`host.createDirectory`, four error codes, and the `describe.directoryPicker` field; the connection fixture serves a deterministic browse tree for keyless assembled tests.
 - A future interaction (or an Electron `dialog` provider) is one backend package plus a client branch — no gateway surgery.
 - `ApiProxyDefaults.pickDirectory` (test-only injection) is gone; tests provide a stub `ctx.directoryPicker` like any other service.
