Stats-bar catalog join + dock numerator consistency (context-meter close-out)

Browse Source 
Platform's context-meter pair (04e336d, 18cc493) left two client seams
in my band; this closes the arc:

1. STATS-BAR CATALOG JOIN: contextWindow's denominator resolves ONLY
   from pi's live catalog — stats-bar now builds the provider:id ->
   contextWindow index client-side (catalogLimits in model-picker.tsx,
   the client twin of the server's catalogContextLimits join) over the
   picker's existing /api/models fetch/cache (useModelCatalog exported;
   module-level dedupe, one fetch feeds both ModelControl and the
   meter). Catalog pending or failed -> undefined index -> limit null ->
   USAGE-ONLY (Platform's interim render IS the null path; the
   honest-render precedent, never a fake window).

2. DOCK NUMERATOR CONSISTENCY: toBlobs' context fold was still
   last-step input+output only — now the same cache-inclusive footprint
   the session meter uses (all four directions; provider "input"
   EXCLUDES cacheRead/cacheWrite, so the old fold read wildly low on
   cache-heavy jobs). Same metric everywhere.

Review of Platform's interim edits in this band: verified as-shipped —
stats-bar's usage-only render (summary + popover), FeedJob.contextLimit
with the line-hides null treatment, and the render-test rewrites all
fit. Only fix needed: none beyond the above.

Tests: catalogLimits pinned pure (index shape, provider:id keying,
missing-model absence); toBlobs pinned on the cache-inclusive
numerator (10k+0.5k+120k+30k = 160.5k against a 200k feed limit).
889/889.

Live-verified on :3001: seedplan's bar reads "18.7k / 1M" (footprint
18725, catalog 1048576); a nope/unknown-model chat renders "12.8k"
usage-only with cost "-"; the popover detail matches; the dock blob's
context line renders "946 / 1M" from a server-joined feed (an
unintentionally real runner-adopted job — the full chain, live).
