feat: add includeInternal option to sync hidden/internal files

[waspeer]

Problem

The bridge currently skips all CouchDB documents whose path contains :, which filters out all files that Self-hosted LiveSync stores with the i: prefix (hidden/internal directories like .claude/, .obsidian/ non-workspace files, etc.).

This makes it impossible to sync tool configuration directories through the bridge — for example, Claude Code stores its skills and configuration in .claude/, which never reaches the storage peer.

Solution

Adds an optional includeInternal field to PeerCouchDBConf — an array of glob patterns (using minimatch) that opt specific i:-prefixed paths back into the sync:

{
  "type": "couchdb",
  "name": "remote-vault",
  "includeInternal": [".claude/**"],
  ...
}

When a document with an i: prefix matches one of these patterns, it passes the checkIsInterested filter and the i: prefix is stripped before dispatching to PeerStorage, so the file is written to the correct filesystem path.

Non-breaking: the option is optional and defaults to the existing behaviour (all i:-prefixed documents are skipped).

Notes

• Sync loop prevention is handled by the existing isRepeating() hash cache — no additional ignore patterns needed
• dat/config.sample.json could be updated to document the new option (happy to add if preferred)
