Retune buildLineBgOverrides for the 1.3.x hover pipeline: per-selector
hover mix rules are gone; hover is now one central rule mixing the
active-line bg 97% (light) / 91% (dark) toward --diffs-hover-mix-target.
Emitted hover --mix-* values are divided by those factors so the final
rendered hover bg shares match 1.2.12 exactly at normal and strong, and
subtle pins the 1.2.x hover finals (deletion 80/75, addition 80/70).
Also add @pierre/theme and @pierre/theming to the bunfig minimumReleaseAge
excludes (review follow-up from #1188).
Swap @atomic-editor/editor@^0.4.3 for @plannotator/atomic-editor@^0.5.0
and bump @plannotator/markdown-editor to ^0.2.0 (its peer dependency was
renamed to the fork). The fork adds proper frontmatter parsing (a leading
--- block no longer misrenders as an HR + giant heading) and the
Obsidian-style Properties widget, with byte-fidelity preserved.
Also exempt @plannotator/atomic-editor from bun's minimum-release-age
gate (same first-party trust as @plannotator/markdown-editor).
Verified: typecheck clean, DOM_TESTS=1 markdownEditorFidelity 4/4,
full suite 1892 pass / 0 fail, review + hook builds succeed.
