Alec Perkins f6b7374be7 Add feature files, image pins and implementations (Phase 4)
Files: prototype and documentation files on features, with versions.
Adding, replacing or removing a file is a feature revision with a
change note. Types come from the extension; uploads are capped at
25 MB and stored under opaque paths. Every file URL checks project
access, then redirects to a short-lived signed URL on the bucket, or
streams with nosniff and a CSP sandbox when no bucket is configured.
HTML prototypes run in a sandboxed iframe without same-origin access.

Threads: whole-file threads and pins at a point on an image, drawn as
an SVG overlay in percentages. Pins are placed with number fields, or
by clicking the image with JS.

Implementations: name, link and status, plus a per-feature status grid
stamped with the feature revision, marked behind when the feature
changes, and confirmable without changing the status.
