shoney.arickathil 47a920f19a feat(serve+view): file serving, downloads, supported systems; rename
- rename the two libraries: writeonce-framework -> writeonce-serve
  (`use serve`), wo-html -> writeonce-view (`use view`). Names say the
  ROLE now; every sample, script, gate and live doc follows
- stories/specs/plans keep the old names: they are dated records, and
  both library READMEs carry a "renamed 2026-08-25" note
- serve/http/files.wo: StaticFiles { dir, max_bytes } — traversal
  refused not normalised, extension content types, attachment
  disposition for archives. Lifted out of the shop, which had said in
  a comment that it belonged in the framework
- shop drops its private copy and mounts the framework's
- site: /dl/*path over $WO_DIST (default ./dist), 16 MiB ceiling
- /install gains supported systems — Linux x86-64, glibc >= 2.38,
  not musl — read off `file` and the binaries' GLIBC_ symbol
  versions, not off a wish list; plus GitHub release as primary,
  /dl as mirror, and the sha256 verify step
- site-accept: 17 -> 21 checks (supported systems, gzip download with
  a binary-safe probe, checksum, /dl traversal 404)

Verified on 192.168.0.165: the real 960,820-byte tarball downloads
as application/gzip and its sha256 matches the published digest.

Gates: oop-accept MET, site 21/0, web-app 46/0, fibers 10/0,
db-actor 8/0; shop rebuilt and its /assets served by the framework.

-- admin.controller.wo — POST /admin/ch/:slug: title/body update,
-- form-encoded, bearer-gated. Mechanism (bearer_token, constant-time
-- ct_eq) is the framework's; POLICY — which routes, which token — is
-- this app's, right here. No rendering: the answer is a redirect.
