Fix end-to-end startup: project registration, credentials, trust dialog, ready marker

- start.sh: auto-register project in ~/.config/context-studio/projects/ before
  launching Electron — without this acquireProjectLock() silently skips writing
  the lock file, waitForServers() never finds the registry port, all agent ports
  stay null (localhost:null errors)

- start.sh: mount all known Claude Code credential locations into container
  (~/.claude/.credentials.json, ~/.claude.json, $CLAUDE_CONFIG_DIR variants)
  not just ~/.anthropic which was empty on this system

- bin/claude: create /tmp/cs-ready-<agentId> on host after 3s delay so CS Core's
  CLI ready marker poll resolves instead of timing out after 10s

- workflow.sh: add hasTrustDialogAccepted:true to all agent settings.json so
  claude goes straight to priming without the folder trust dialog

- prereqs.sh: add ensure_api_key() — checks all credential locations, prompts
  with masked input if none found, offers to save to shell profile

- wizard.sh: trap SIGINT for graceful abort — gum confirm popup, reverts created
  project dir and cloned core dir, leaves installed packages untouched

- core.sh: set _WIZARD_CORE_CLONED=true before clone for cleanup tracking

- electron-config.js: increase serverStartupTimeout 30s→90s (config file in
  core/config/, not source — safe to edit)

+1. `ANTHROPIC_API_KEY` environment variable
+2. `~/.claude/.credentials.json` (default `claude auth login` location)
+3. `~/.claude.json`

+If none found, you're prompted to enter an API key (masked input) with an option to save it to `~/.zshrc` / `~/.bashrc`.
+
+All credential files that exist are **mounted read-only** into the container so Claude Code can authenticate.
