Commit Message

Document the file-read clone cost and the reusable signer's long-lived key tradeoff

`WriteBuffer::file_get` now notes it clones on every call, not once per edit: the target workload is a burst of edits (each `file_put` supersedes the last) within one transaction, not reads, so a future caller looping reads over a freshly buffered value would re-clone the full blob each time and should cache the bytes itself.

`crypto::Signer` now notes the tradeoff of holding the expanded signing key for the owning session's whole life: a slightly larger long-lived secret footprint bought for the per-signature speed-up, but not a wider exposure, since the session already keeps the signing seed unencrypted for its whole life and the expanded key is trivially derivable from it.
