Replace the marker-filled three-pane resolver with a marker-free native
Draft versus frozen Alternative projected from current working text.
Preserve preexisting outside edits, native undo, dirty-save guards, all
sides/bases, and draft caret/viewports across separate History views.
Reuse DiffState alignment/highlighting/excerpts for Resolution and merge
its base-aligned rows for readonly three-way History. Hide explorer and
source-selector chrome by default.
Verified 926 tests plus actual terminal projection, History highlighting,
hunk choice, optional explorer, and guarded jj-confirmed save workflows.
Clippy completes with pre-existing warnings only. Smoke fixtures stay
unresolved in this ancestry; remove that ancestry before publication.
Size exception: approximately 1650 implementation added/deleted lines,
excluding tests/docs, kept coherent because native draft lifecycle and
aligned rendering must change together without parallel legacy modes.
Conflicted revisions read every file through jj file show, which returns
empty output for symlinks and causes repository-wide subprocess fanout.
Keep ordinary Git blob sources and immutable identities; render only
selected conflicted paths through jj.
Verified all 905 tests and the original local bookmark comparison with
25 correct paths in 0.522s, plus actual terminal conflict viewing.
Strict Clippy is blocked by existing diagnostics outside this change.
