chore(deps): bump weave to 0.16.6

[rgao-coreweave]

Bumps weave from ^0.16.3 to ^0.16.6. Dependency only, no code change.

Branch is still named bump-weave-0.16.5 from the first push. Graphite refuses to rename a branch with an open PR, and forcing it would orphan this PR and rebase the two above it, so the stale name is left alone.

What is new, and what we use

Diffed the published dist across 0.16.3 → 0.16.5 → 0.16.6 rather than trusting changelogs. 0.16.6 is by far the larger of the two releases.

Adopted at the top of this stack

• Turn.record({ outputMessages }) (0.16.5) and SubAgent.record({ messages, outputMessages }) (0.16.6). The SubAgent half is what makes the migration complete rather than partial, so all five gen_ai.output.messages writers move together.

Available, not adopted here

• Tool.end({ result, errorType }) and args?: JsonObject | string. 0.16.6 deprecates the tool.result = setter, which we use at three sites in callLifecycle.ts. Still functional, so this is a follow-up rather than a blocker. Flagged below.
• JsonValue / JsonObject exported types. We already define our own in callLifecycle.ts.
• opLinkSpanProcessor, evalLinkSpanProcessor changes. Eval/op linking, not used here.

Not applicable

• flush() / client.flush() / pendingCallCount() / useCallsComplete: classic Weave calls batch path. We emit only OTel genai spans and already use flushOTel().
• registerCustomRuntime() + CustomRuntimeId: custom inference-runtime registration.
• WEAVE_INTEGRATION_NAME / _VERSION / _META_PREFIX semconv consts: not exported from the public entrypoint (only via a deep internal import). The strings we hand-roll in genaiSpans.ts already match the canonical values exactly, so they are now upstream-validated.

Follow-up worth filing

tool.result = is deprecated in favour of end({ result }), and end() now takes errorType which maps to error.type (we set that attribute by hand). Happy to send that as a fourth PR on this stack.

Verification

npm ci && npm run check

tsc clean, 203/203 tests pass.
