Films reach the site the same way stills do

Browse Source 
`films.mjs` now writes into the sibling lumbridge-v4 checkout — the MP4s and
their posters into `apps/web/public/films/`, and a generated `films.ts` beside
the shots manifest, carrying each reel's caption, alt text and running time.
Same shape as `shots.mjs`, including the `FilmId` union that turns a page
naming a deleted reel into a typecheck failure rather than a dead <video>.

`--publish <dir>` puts an existing render in front of the site without
re-shooting it. Twenty-two minutes a reel is long enough that the alternative
would have been `cp`, and a hand-copied artefact is the thing this pipeline
exists to not have. `--frames` refuses to publish at all: a 24-frame stutter is
a rough cut, not something to put on a website by accident.
