Implementation Specification

Build an API that creates context items.
create_context_item(
context_type,
title,
content,
source=None,
tags=None,
importance=1
)
This function should save a context item into the SQLite database.

Example context item:

context_type: config_decision
title: Database choice
content: We chose SQLite because it is local, lightweight, and works offline.
source: week-02-discussion
tags: sqlite,database,local-first
importance: 5

2. The item receives a unique ID.
3. The item stores context_type correctly.
4. The item stores title and content correctly.
5. The item stores created_at and updated_at.
6. Empty title is rejected.
7. Empty content is rejected.
