Bug: extensions directory not included in package build

[rhnvrm]

Description

The gateway-install.sh script doesn't copy the extensions/ directory to the output, even though it exists in the source at the pinned commit. This causes built-in channel plugins (Discord, Telegram, etc.) to not load.

Environment

• nix-clawdbot: latest main branch
• Pinned source: commit c21469b282213cbcc1858921dc668b1cc5e29f7e

Root Cause

In nix/scripts/gateway-install.sh, only these directories are copied:

• dist
• node_modules
• package.json
• ui

The extensions/ directory is missing from this list.

Impact

Channels like Discord don't load because the plugin registration code lives in extensions/discord/. The core Discord functionality exists in dist/discord/ but without the extension wrapper, it's never registered as a channel plugin.

Gateway logs show no Discord initialization - channels list shows empty.

Workaround

Manually extract extensions from the pinned commit to ~/.clawdbot/extensions/:

mkdir -p ~/.clawdbot/extensions
cd ~/.clawdbot/extensions
curl -sL 'https://github.com/clawdbot/clawdbot/archive/c21469b282213cbcc1858921dc668b1cc5e29f7e.tar.gz' \
  | tar xz --strip-components=2 'clawdbot-c21469b282213cbcc1858921dc668b1cc5e29f7e/extensions/discord'

Then restart the gateway - Discord will load from the global extensions directory.

Suggested Fix

Add extensions to the copy list in gateway-install.sh:

cp -r dist node_modules package.json ui extensions "$out/lib/clawdbot/"
