dashboard: the build pages are tabs of the dashboard

Browse source 
The build lifecycle used to be its own page with three sub-tabs. They are
now dashboard tabs (rebuild, meta, buildlogs) beside SW4RM and
P3RM1SS10NS: builds.js is a module tabs.js imports, so the dashboard's one
tab strip, /api/state snapshot and event stream (plus the meta_inputs_changed
and meta_update_running kinds) serve them, and the page, its bundle entry,
stylesheet and home tile are gone. The SW4RM banner's "view queue" link
points at the #rebuild tab, and the rebuild tab carries a count pill of the
rebuilds in flight.

An empty tab-count pill drew a "0": its display beat the UA [hidden] rule.

// BU1LDS page entry (/builds.html). The build lifecycle hub — rebuild
// queue, live build log, meta inputs, and build log history on one page.
// Three sub-tabs via <hive-tab-strip> (default = Rebuild Queue):
// - R3BU1LD QU3U3: pending + running rebuilds + live build log inline
// - M3T4 1NPUTS: nix flake input selector + meta-update trigger
// - BUILD L0GS: all-agents build log history (lazy-loaded on tab show)
// The build lifecycle tabs of /dashboard.html — rebuild queue, live build
// log, meta inputs, and build log history. Not an entry point: tabs.js
// imports it, owns the tab strip and the dashboard event stream, and calls
// the exports below. Three tabs, the panes' ids matching the tab ids:
// - rebuild (R3BU1LD QU3U3): pending + running rebuilds + live build log
// - meta (M3T4 1NPUTS): nix flake input selector + meta-update
// - buildlogs (BUILD L0GS): all-agents build log history, lazy-loaded
// the first time the tab is shown
