Semantic Todoist Sync 0.8.29

Automatically self-heal semantic-index queues and align Open WebUI model limits.\n\n- Schedules and retries pending semantic-index flushes so compatibility rebuilds and transient failures cannot strand vault evidence retrieval.\n- Coalesces large pending bursts into one rebuild instead of hundreds of serial per-file embedding jobs.\n- Reads nested Open WebUI/llama-server context metadata and uses the discovered model window for chat and task preflight budgets.\n- Extends the bounded generic Open WebUI execution deadline for evidence-rich local prompts.\n- Adds regression coverage for queue scheduling, nested model context discovery, and adaptive input budgets.\n\nValidated with
ode --check main.js,
ode --check scripts/openwebui-carrier-recovery-local-test.js, 114 local assertions, git diff --check, and an Obsidian smoke reload.
