feat: Chrome Performance panel tracks for Solid (@solidjs/web/performance-tracks) (#3580)

* feat(web): Chrome Performance panel tracks for Solid — engine foundation, adapter, timeline records

Stage 0 — shared engine foundation (@solidjs/signals, @solidjs/web):
- attribution.enable()/disable() are ref-counted: the engine is shared by
  every consumer on the page (a profiler track, an APM adapter, a
  diagnostics capture); the first hold installs, each enable() opens a fresh
  window over the ring buffers and folds without disturbing live tracking or
  others' subscriptions, the last disable() uninstalls.
- `checks` option: one switch for the five thresholded cost checks, for
  records-only consumers.
- isSilentHold / isLongHold exported, so adapters paint the engine's own
  verdicts rather than re-deriving thresholds.
- dispatchAsInteraction passes at: e.timeStamp; InteractionEvent gains
  inputDelayMs (event creation → handler entry, the INP input-delay term) and
  handlerMs measures from the handler's actual start.
- ownerPath re-exported from solid-js (client from @solidjs/signals, server
  via the ownerLabels twin).

Stage 1 — @solidjs/web/performance-tracks:
- enablePerformanceTracks() paints rerun / interaction / hold / navigation
  records and the web runtime's call / frame records as tracks in the
  `Solid` group, retroactively from the records' own performance.now()
  stamps: performance.measure with detail.devtools (rich: tooltips,
  properties; dev default) or the six-argument console.timeStamp (observe
  default). Track seeding for stable display order, minMs floor, scrub mode
  for shared traces, ref-counted disable. Prod artifact folds to a no-op.
- rollup dev/observe/prod entries, ./performance-tracks export conditions,
  types script.

Stage 2 — timeline records (@solidjs/signals, solid-js, @solidjs/web):
- Five listener-gated records on attribution.subscribe: create (a
  computation's creation run), effect (an effect callback, timed ... (continued)
