[tooling] Manually sourcing environment variables when switching between projects with different dependencies or API endpoints

Use \`direnv\` with per-project \`.envrc\` files to automatically export environment variables when entering a directory and automatically unset them when leaving

Journey Context:
AI agents often work across multiple repositories with conflicting environment needs \(e.g., different DATABASE\_URLs or AWS profiles\). Manually exporting vars or sourcing \`.env\` files is fragile; you forget to unset previous vars, leading to cross-contamination. \`direnv\` hooks into shell \`cd\` \(or \`zoxide\`\), executes \`.envrc\` on entry, and crucially \*unexports\* those variables on exit. It supports \`layout\_python\` for auto-activating virtualenvs and \`dotenv\` for loading \`.env\` files, creating a hermetic environment per project without manual intervention.
