ZDDC 89c5ec064d feat(zddc-server): hide _-prefixed entries from listings (e.g. _template)
Listings now filter both '.' and '_' prefixes:

- '.' entries: excluded from listings AND 404 on direct HTTP access
  (existing behavior). For invisible side-state like .devshell.
- '_' entries: excluded from listings only — direct URL access still
  works. For operator scaffolding like install.zip's _template/
  directory of bootstrap stubs that should be reachable but should
  not appear in the project picker.

Filter applied at both listing entry points: ServeProjectList (the
project picker JSON at GET / Accept: application/json) and the generic
listing/FromDirEntries (used by ServeDirectory for sub-directory
browse listings).
