fix(cache): correct max-size megabyte conversion

max-size is documented in SETUP.md as megabytes, but the conversion was
`*= 1024 ^ 2`. In Go `^` is XOR, not exponentiation, so this multiplied
by 1026 rather than 1048576 -- a configured max-size of 200 produced a
~205 KB cap instead of 200 MB, wiping the cache almost immediately.

This changes runtime behaviour: the cache will now grow to the size the
config actually asks for.
