Cleanup skill logic files and update deployment scripts

feat(provision): dynamic browser support and installer resiliency ...

- Added browser support toggle to one-liner UI.\n- Updated provision endpoint to handle skip_browsers and disable skill in config.\n- Improved installer to handle --skip-browsers and avoid hardcoded URLs.\n- Added safeguards to browser skill to prevent whole-agent crashes.\n- Enabled invite_token auth for agent updates.\n- Bumps version to 1.0.15.

feat(installer): add automatic playwright browser installation ...

- Makes the one-liner truly 'batteries-included' for browser automation.\n- Bumps version to 1.0.13.

fix(installer): look for config in install_dir to prevent identity reset

fix(bootstrap): add pip bootstrapping and resilient dependency install ...

- Attempt to use 'ensurepip' if pip is missing (common on Synology/OpenWRT).\n- Support --user fallback for dependency installation.\n- Bump version to 1.0.8 to sync improvements to all nodes.

fix(bootstrap): add custom YAML parser to installer for resilience ...

- Allows installer to read agent_config.yaml even if PyYAML is not installed.\n- Fixes 'token required' error on fresh headless nodes (Synology/OpenWRT).

fix(agent): handle read-only mounts in installer and bump to 1.0.7 ...

- Installer now skips files it can't delete (like read-only Docker volumes).\n- This allows test nodes to successfully update.

fix(agent): correctly handle directory structure during extraction ...

- The Hub now wraps the agent bundle in an 'agent-node/' prefix.\n- The installer now only strips the 'agent-node/' prefix if present, preventing it from accidentally deleting the 'src/' folder.

fix(agent): robust daemon install and gRPC config ...

- bootstrap_installer now forces config overwrite during daemon setup to prevent stale token reuse.\n- ai-hub now preserves gRPC port in generated config, preventing agents from defaulting to localhost.\n- installer now ensures gRPC endpoint always has an explicit port.

fix(agent): make bootstrap installer resilient to pip meta errors ...

- Adds --ignore-installed to dependency installation to bypass metadata/RECORD file errors often found in Anaconda and system Python environments on macOS.

fix(agent): separate hub vs node authentication tokens in bootstrap installer ...

- bootstrap_installer now uses 'secret_key' for HTTP hub requests (version/download) and correctly preserves/restores the node-specific 'invite_token' (auth_token) for gRPC.

fix(agent): bootstrap installer auth token precedence ...

- Fix 401 Unauthorized during upgrades by having bootstrap_installer check for `secret_key` in agent_config.yaml before falling back to `auth_token`, since the /api/v1/agent/version endpoint expects the Hub's global SECRET_KEY rather than a node's specific invite token

refactor: organize agent-node client code structure by moving core packages to src/ ...

- Moved agent_node, protos, and shared_core inside src/

- Updated Dockerfile, deployment scripts, compile_protos.sh, installers

- Updated bundle generation in ai-hub to reflect cleaner structure and better README

feat: add daemon/service installation for Mac and Linux ...

- Added install_service.py to configure launchd on macOS and systemd on Linux

- Added --daemon flag to bootstrap_installer.py which acts as a simple 1-click install

feat: add swarm control chat history clear & agent node auto-update system ...

- Added API and UI to clear chat history in Swarm Control while preserving node sync

- Implemented HTTP-based auto-update agent bootstrapper and core daemon

- Removed unused workflow profile and orphaned voice-interaction-handler skill

- Fixed voice chat response duplication and tool-belt instructions
