Committed before review so Windows and WSL builds can start. Each fix was tested and mutation-checked here; the codex review of each item is still to come, so tasks/BUGS.md stays unticked. M-02 is mid-review: round 1 findings are fixed (apps/ely-mark/src/tally.rs). K-01 stays deferred. The ElyMark window test mark-outside.sh failed once at its crash-recovery step in the last run; not yet looked into.
