Guard Merge against mock transcripts

[isaiahb]

Summary

• Skip Local Merge AI analysis for deterministic cloud-v2 mock transcript text while still recording the transcript/activity.
• Remove a stale Bluetooth SDK public export for setCaptureLedEnabled, which was intentionally removed from the native SDK path.

Validation

• bun run --cwd miniapps/merge build
• bun run --cwd mobile/modules/bluetooth-sdk prepare
• bun install --frozen-lockfile
• git diff --check

Notes

PR #3178 was squash-merged while this fix was being made, so this is the small follow-up against current dev.

Note

Low Risk
Behavioral guard in Merge miniapp and removal of an unused SDK binding with no auth, security, or data-path changes.

Overview
Merge now detects cloud-v2 mock transcripts (via source/provider === "mock" or deterministic mock … <n> text), still upserts and broadcasts them, records a silent decision, and returns before final/interim insight analysis so the backend is not called for test traffic.

The mobile Bluetooth SDK public surface drops setCaptureLedEnabled, which no longer exists on the native module after an intentional removal.
