feat: add the obsidian connector for nao cli [nao-cli]

[Francois-lenne]

Why

NAO already ingests context from local databases, git repos, and Notion, but it has no first-class way to pull in local Obsidian notes.

This PR adds a simple Obsidian V1 focused on the core use case: sync Markdown notes from a local vault into the nao context, using the same overall pattern as the existing Notion
integration.

What

Adds a new obsidian integration to the CLI:

• new obsidian config block in nao_config.yaml
• interactive setup prompt in nao init
• new sync provider that copies vault .md files into docs/obsidian/
• ignores .obsidian/ and non-markdown files
• preserves the vault directory structure
• removes stale synced notes
• exposes synced notes in templates via nao.obsidian.note(...)

Example config:

obsidian:
path: /path/to/your/obsidian-vault

This V1 intentionally does not handle Obsidian-specific semantics yet ([[wikilinks]], embeds, assets, .canvas, backlinks, etc.).
