Prettier reformatting on files touched in the wave 11.B sequence —
markdown italics _underscore-style_, single-line conditionals, minor
whitespace fixes. No semantic changes. .env.example reformatting left
unstaged (blocked by pre-commit hook).

renameFolder + moveFolder enforce sibling-name uniqueness via the
shared isSiblingNameConflict helper and reject cross-port leakage at
the service boundary. moveFolder walks the destination's ancestor
chain to refuse cycles before the write.
deleteFolderSoftRescue re-parents every child folder and document up
to the deleted folder's parent (or to root) inside a transaction,
then drops the folder row. Children never disappear silently — a
wrong click moves work up the tree, never deletes it. Audit-logged
with rescuedTo metadata.
