MCP Config File Atomic Writes

Entry
JSON All of v2.1.59
EntryKind: in v2.1.59,
ChangesSection of the release

Writing .mcp.json now uses atomic file writes (write to temp file, then rename) to prevent corruption if the process is interrupted mid-write.

Evidence

Atomic write helper (search for ".mcp.json" in added function Vw7)

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
