* fix(plugins): close trust-boundary holes in the plugin system
Move five security decisions to their chokepoints rather than leaving them
enumerated at individual call sites.
- Kill-list revocation reaches content packs: PluginContentPackRegistry now
takes an isKilled predicate and intersects it with any caller-supplied
approval, so a killed plugin's VM recipes can no longer reach
spawn(..., { shell: true }) through either reconcile() call site.
- Bound kill-list generatedAt to a 24h future skew at the parse chokepoint.
A far-future timestamp previously made every genuine later list look
"older" and disabled revocation permanently, persisted across restarts.
- Protect the whole auto.components.settings.Plugin* translation subtree
instead of an enumerated prefix list, so language packs cannot forge the
consent provenance badge or rewrite install-error security copy.
- Resolve manifest panel icons by own-key only; "constructor"/"__proto__"
previously yielded non-component prototype members that crashed the
right sidebar to its error boundary.
- Give panel liveness frames a reserved control budget so a panel that
saturates its action budget can still answer the watchdog.

* fix(plugins): keep the kill-list future bound off the cache read path
The schema-level generatedAt bound re-judged the on-disk cache against the
device clock at every launch, so a client whose clock ran behind the last
genuine publication discarded its whole cached kill list and started with
zero revocations. Move the bound to the two fetch chokepoints instead.

* fix(plugins): remove the reserved-lane starvation window and the revocation TOCTOU
Review follow-ups on the trust-boundary fixes:
- The reserved liveness lane had a per-window count equal to the ping
interval, so a panel's own pong-shaped traffic could spend it and drop
the next genuine reply — reintroducing the starvation the lane exists to
prevent. The lane is now size-bounded only; rate stays bounded because
every pong is also charged to the data budget.
- Only schema-valid pongs take the lane now, so near-miss pong-shaped junk
cannot drain it. readPanelPongId replaces the zod parse on this
guest-controlled path (a rejected safeParse allocates an issue list, ~90x
the accepted-path cost) and is pinned to the schema by a parity test.
- Re-read the kill list inside approveAtomically: approvedKeys is snapshotted
before an awaited verification phase, so a plugin killed during that wait
could still publish VM recipes and language packs.
- Assert the curated icon resolves to FileText; the old equality also passed
when both sides fell back to Plug.

* fix(plugins): match zod's safe-integer bound in the pong reader
readPanelPongId used Number.isInteger, but zod's .int() rejects anything
above 2**53-1, so pingIds like 1e100 took the reserved lane the schema
would have refused. The parity test never probed that boundary.
