docs: replace the navi-SAD bridge with a generic Measured Data page

[Fieldnote-Echo]

navi-SAD is being retired. The bridge page's account of what these theorems do and do not establish for measured time series is kept as Exposition > Measured Data, with every navi-SAD reference removed (the index row and the Delay Embedding tip now point there). check_docs_site.py now lists navi-SAD and navi-fractal as retired names, so the built site fails the check if either reappears. Docs site check, doc-name check and 63/63 checker tests pass locally.

High-Level Assessment

Keeping the existing theorem guidance while removing its project-specific framing is appropriate. Retaining the old bridge in navigation would undermine retirement; the new page provides a clear destination for updated links.

Add a failing fixture for the newly retired names

The checker test still exercises only debt.md, so scripts/test_checkers.py passes even if any of these new entries is misspelled or later removed. Add a fixture containing the newly prohibited navi-SAD/navi-fractal names so this new gate is actually regression-tested, as required for checker changes.
