fix: serialize property writes and expose n8n results

- Serialize property set and remove commands per vault note to avoid lost frontmatter writes.
- Wait briefly for successful property writes to hit disk before releasing the note lock.
- Return property path, name, value, type, operation, and ok status in n8n outputs.
- Include property details on continue-on-fail errors so failed items are visible in n8n.
- Bump obsidian-api to 1.0.7 and n8n-nodes-obsidian-cli-api to 0.2.8.
- Add regression coverage for concurrent property writes to the same note.
