feat: add Claude Code web session setup with gh CLI and worktree support (#8249)

* feat: add SessionStart hook for Claude Code on the web

Adds a session-start hook that runs in remote environments to:
- Install all dependencies (npm run install:all)
- Generate gRPC/protobuf types (npm run protos)

This enables Claude Code web sessions to properly run tests and linters.

* feat: add .worktreeinclude for Claude Code worktrees

Ensures environment files and local settings are copied to new worktrees:
- .env files
- .clineignore
- Local Claude settings

* fix: include node_modules and generated files in worktreeinclude

Copying these to worktrees saves significant setup time:
- node_modules: skips npm install (~1-2 min)
- src/generated/, src/shared/proto/: skips proto generation

* feat: install gh CLI and add GITHUB_TOKEN support in session hook

- Rename session-start.sh to claude-code-for-web-setup.sh
- Install latest gh CLI from GitHub releases
- Check for GITHUB_TOKEN and inform Claude about gh availability
- Enables using `gh issue`, `gh pr` commands when token is configured

* refactor: make .worktreeinclude a symlink to .gitignore
