* Add roadmap timeline view for GitHub Projects
- Renders roadmap-layout project views as a scrollable timeline with
date/iteration-based placement, zoom levels, and grouped lanes,
instead of surfacing them as unsupported
- Derives placement fields from view config or row-carried field
values since GitHub's API never exposes a roadmap's date source
directly
- Falls back to the existing table list when no field can place items
* Fix roadmap timeline edge cases: reject invalid calendar dates and refre
- parseRoadmapDate previously let Date.UTC silently normalize overflowing
dates (e.g. 2026-02-30 → Mar 2); now round-trips components to reject them
- ProjectRoadmap's "today" marker was frozen at mount, so panes left open
across midnight showed the wrong day; now re-derives and re-arms a timer
* fix(github-projects): center roadmaps when dated rows arrive
* fix(github-projects): keep pinned roadmap header opaque
* fix: remove stale pnpm executable lockfile entries
* fix(i18n): retain replaced project labels in runtime catalog
