R2 PutObject requires Content-Length header. Buffer files <100MB into

pattern regex escaping for slug input.

Uploaders can optionally set a custom path via the "slug" field.
Slug appears before the file in multipart form so it's available
before streaming begins. Validated: alphanumeric + hyphens/dots/
underscores, 1-64 chars, checked for uniqueness.
