Accounting for non-mergeable EmuFlight 1.0.0 BF-fork PRs

AI Generated issue-ticket

EmuFlight 1.0.0 was a planned major milestone — a clean rebase onto a newer Betaflight fork with architectural improvements. That milestone was never completed, and the active development path has moved on. The PRs listed below were opened specifically targeting the 1.0.0 label and represent work-in-progress features that cannot be cleanly merged into current master in their present state.

This issue exists to acknowledge and document that work before the PRs are closed for backlog hygiene. The ideas here are not lost — they are captured below and may inform future work.
