RagavRida ac89d8847e fix(meta-commands): guard JSON.parse in pdf --from-file parser
parsePdfFromFile() runs JSON.parse on user-supplied file contents with
no try/catch. A malformed payload surfaces as an uncaught SyntaxError
from the 'pdf' command handler and the user sees an opaque stack trace
instead of "this file isn't valid JSON". Worse, the same call path is
used by make-pdf when header/footer HTML would overflow Windows'
CreateProcess argv cap, so a corrupt payload file there can take down
the make-pdf run.

Wrap JSON.parse. Re-throw with a message that names the offending file
and echoes the parser's own explanation. Also reject top-level non-
objects (null, array, primitive) since the rest of the function treats
json as an object — catching that here produces a clear error instead
of a TypeError further down.
