fix: parallelize loader upserts

[Teagan42]

What

• stream loader Qdrant upserts through bounded background workers so ingestion continues while batches persist and errors bubble up safely
• adjust the loader logging concurrency test to wait deterministically for queued batches
• bump the project version metadata and refresh the uv lockfile

Why

• the previous scheduling awaited Qdrant batches inline once the concurrency limit was reached, which made point writes effectively synchronous with metadata fetching
• keep the recorded package version consistent across manifests

Affects

• loader Qdrant upsert pipeline and concurrency-focused tests
• project version metadata

Testing

• uv run pytest
• uv run ruff check .

Documentation

• no documentation changes needed

Pull Request Overview

This PR refactors the loader's Qdrant upsert pipeline to parallelize operations through background workers instead of awaiting inline, improving performance by allowing ingestion to continue while batches persist. It also fixes test synchronization and updates version metadata.

• Replaces synchronous task scheduling with bounded background workers for Qdrant upserts
• Updates concurrency test to use deterministic waiting instead of non-blocking queue operations
• Bumps project version from 0.26.53 to 0.26.55 across manifests
