fix(mcp): report references a provider truncated in trace_feature (#2348)

* test(mcp): expect trace_feature to report references the provider truncated

A provider that reports a capped xrefs read makes the trace truncated with a residual unknown for that target. An explicit complete report and a provider that reports nothing leave the trace as before.

* fix(mcp): report references a provider truncated in trace_feature

Executions gain an optional flag for a capped xrefs read, set by the IDA adapter from the upstream cap. trace_feature marks the trace truncated with a residual unknown for that target only when the provider reports a truncation; a provider that reports nothing keeps its previous result. The trace_feature workflow profile is revised so earlier results are not replayed.

* refactor(ida): report reference truncation whenever the runner observed an xrefs cap

* test(mcp): cover session forwarding, per-target state, native reports and failures of the trace coverage

* test(mcp): format the session forwarding test

* test(process): format processCaptureLifecycle.test.ts after the merge

* test(ida): declare the alignment each synthetic universal slice offset satisfies

* fix(process): report no remaining time after a provider deadline fires

Node timers can fire while performance.now() is still a fraction of a
millisecond short of the monotonic deadline. ProviderStartupDeadline then
reported interruption "timeout" and an aborted signal while remainingMs()
returned ceil(0.x) = 1, so polling loops guarded by remainingMs() > 0
(Hopper and Ghidra startup) could run past an elapsed deadline, and the
real-timer test "aborts a bounded wait when its real monotonic deadline
expires" failed intermittently in CI (expected 1 to be 0).

Once the deadline's own timer has classified a timeout, report zero
remaining time. A deterministic regression test fires the timer with the
monotonic clock 0.4 ms short of the deadline.
