feat(workspace): complete shared inspector and collection viewer (#224)

* feat(inspector): expose bounded physical file evidence

* fix(inspector): distinguish ambiguous saved associations

* feat(inspector): derive conservative generation facts

* fix(inspector): guard fact ancestry and inspection state

* feat(inspector): share complete file details and exports

* fix(inspector): preserve fact states and touch targets

* feat(viewer): navigate the loaded media collection

Refs #216

* fix(viewer): refit after current stage geometry changes

Ref #216. Observe the current media stage after readiness and wrapped title changes without rebuilding focused controls or resetting transforms at unchanged dimensions.

* feat(viewer): add lifecycle-safe slideshow and media preferences

* fix(viewer): resume gallery continuation after close (#216)

* fix(images): guard source recovery and wrap viewer actions

Clear stale root and folder intent, cancel old pages, and wait for current source discovery before loading a refreshed collection. Preserve safe retry through failed, superseded, and disposed discovery.

Wrap narrow viewer footer actions and wait for measured gallery viewport settling in responsive checks. Refs #216; addresses PR #224 review.

* test(viewer): await gallery layout after viewport changes

Require actual inner, root client, and document widths to agree after each responsive-case viewport and CSS zoom transition. Keep the existing exact frame, overflow, focus, and coarse target assertions unchanged.

Observed PR #224 CI initial mobile resize at537px before pending card relayout settled to356px. Refs #216.
