improvise-6yvg reproduced. A JSON import in improvise-command and a legacy
JSON .improv load in improvise-io stored 0.24815714285714285 as
0.24815714285714283 in each crate's own test build. The root binary's
`improvise import` used the same lossy parser. Now float_roundtrip is on every
normal serde_json dependency in the workspace: root, improvise-command,
improvise-io, and the optional test-support dependency of improvise-protocol.
improvise-dz8c: the hand-listed cargo-tree check over three frame-parsing
crates is replaced by tests/json_numbers.rs. It reads
`cargo metadata --no-deps` and names every package, including target-specific
entries, whose normal serde_json dependency lacks the feature. The rule and why
it beats "parses a frame", the build graph, and enabling the feature once in
the protocol crate are in context/code/protocol.md.
