adjust had no way to report that an edit does not affect a formula, so
callers copied, rebuilt and printed every formula in the workbook.
adjust_if_changed borrows the formula and returns None when nothing
moves. Its check reuses adjust_ref on each reference into the edited
sheet, on a copy without the sheet name, so it cannot disagree with
adjust. adjust_ref and shift_ref take the reference by value and no
longer clone sheet names.
An integration test keeps the previous implementation as an oracle
over every edit kind and a randomized property test.
Fixes#3576

* CI: dev builds keep line tables only
* CI: one integration-test binary per crate
* CI: xtask runs tests with nextest, doctests apart, --keep-going on clippy and wasm
cargo xtask test runs the workspace tests (--lib --bins --tests) with cargo-nextest when it is installed, else cargo test, then the doctests. cargo xtask ci uses the same two steps.
* CI: docs name cargo xtask test
* CI: agent guides name the moved fuzz test
* CI: tests added on main join their crate's test binary
