Allow title-only updates without requiring markdown body

[fajarmf]

Problem

Currently, slite_update_note requires the markdown parameter even when only updating the title. This forces users to:

1. Fetch the full note content first
2. Send the entire body back just to change the title

This is inefficient and error-prone for simple rename operations.

Current Behavior

required: ["noteId", "markdown"]
title: optional

Proposed Solution

Make markdown optional in slite_update_note. If not provided, only update the title while preserving existing content.

required: ["noteId"]
// At least one of title or markdown should be provided

Use Case

Renaming weekly notes from inconsistent naming to standardized format:

Current Name	New Name
Week of Dec 22, 2025	2025 - W52 - Dec 22
weekly update 29 dec	2026 - W01 - Dec 29
Week of Jan 6, 2026	2026 - W02 - Jan 5

Currently this simple rename requires fetching and re-sending the full markdown body for each note.

I think this might be covered by the diff updates in my upcoming PR

Hi @fajarmf I spoke to the founder of Slite and it sounds like they're going to be bringing their own MCP out soon so I'll probably pause for the time being. Thought it would useful for you to know.

I tried to merge my changes and they were running into tons of merge issues, so I think the codebases have diverged too much now unfortunately.

If I get time to look into it I will, though as you can imagine it's dropping down my priority list now.

No problem @gazreese . Thank you for letting me know.
