[Bug] CLI: File chunks not replicated to remote - files appear empty (size 0)

Bug Description

When using the LiveSync CLI to push files to the local database and then sync to a remote CouchDB, the file metadata is replicated but the content chunks are not. This results in empty files (size 0) on the remote database.

Environment

• LiveSync version: 0.25.54 (CLI built from main branch)
• Node.js: v24.14.0
• OS: Linux (VPS)
• Remote: CouchDB on Synology NAS via nginx reverse proxy

Steps to Reproduce

1. Build and run the CLI:

cd src/apps/cli
npm run build
node dist/index.cjs /path/to/local/db --settings /path/to/settings.json push /source/file.md "vault/path/file.md"

1. Verify file is in local database with content:

node dist/index.cjs /path/to/local/db --settings settings.json info "vault/path/file.md"

Output shows: size: 13325, chunks: 12, children: [h:+odnnbu1n8yob, ...]

1. Sync to remote:

node dist/index.cjs /path/to/local/db --settings settings.json sync

1. Check remote via curl:

curl -u user:pass https://couchdb/db/f:hash | jq '{_rev, size}'

Output shows: size: 0 (empty file)

1. Verify chunks are missing on remote:

curl -u user:pass https://couchdb/db/h:+odnnbu1n8yob
# Returns: {"_id": null, "_rev": null} (not found)

Expected Behavior

Both file metadata AND content chunks should be replicated to the remote CouchDB during sync, making the file accessible to other devices.

Actual Behavior

• File document is created on remote with revision bumped (e.g., 4-5c7a...)
• File size field is 0 on remote
• Chunk documents (type h:+...) are not present on remote
• Other devices see the file entry but cannot retrieve content

Additional Context

• Settings used: readChunksOnline: true, encrypt: true, liveSync: true
• The local database correctly stores chunks (verified via info command)
• Sync reports [Done] Command 'sync' completed with no errors
• Obsidian plugin sync works correctly between laptop/mobile and same CouchDB
• This appears to be CLI-specific; the plugin's sync logic properly handles chunks
