Detailed Description

RAII scope guard for transient scratch borrows.

Marks the arena on construction and restores it on destruction, so every scratch_alloc() made within the scope is reclaimed on every exit path (return, break, fall-through) - the safe way to borrow transient scratch in a function with multiple returns. Scopes must nest (LIFO); the per-dispatch scratch_reset() is the backstop if one is ever skipped.
