* fix: prevent unbounded read in Terraform remote configuration loader (GHSA-fmgp-q6jx-gg3x)

* fix: bound remote Terraform clone and invalidate cache on rejection

Follow-up hardening for GHSA-fmgp-q6jx-gg3x.

Bound the clone of the attacker-supplied repository: shallow Depth:1, a
2-minute fetch timeout via PlainCloneContext, and post-clone caps on the
retained tree size (64 MiB) and file count, rejecting and removing a clone
that exceeds them.

Invalidate the clone cache: re-clone when the recorded remote URL changes,
and remove the cache on a failed clone or a rejected read so a corrected
repository is re-fetched instead of a poisoned or stale tree being reused.

Validate the module name before building the cache path, and log clone,
rejection, and eviction events.
