Add --skip-install and --skip-validation to ucode configure

[dhruv0811]

Summary

ucode configure always (1) installs/updates the agent CLIs and (2) runs each one with a test message after configuring. For callers that only need the workspace auth + AI Gateway routing written to ~/.ucode/state.json, and that manage the agent binaries themselves, those two phases are unwanted overhead — they download/update binaries, surface an interactive "update Codex?" prompt, and spend time/tokens validating agents the caller never launches through ucode.

This adds two opt-in flags so a programmatic consumer can run just login + Gateway configuration:

• --skip-install — don't install or update the agent CLIs.
• --skip-validation — skip the post-configure check that runs each agent with a test message.

Concretely, this unblocks embedding ucode configure inside another tool: it can wire up Databricks model serving (login → Gateway discovery → state.json) without ucode touching the user's locally-installed agent binaries or running validation prompts.

Behavior

• Both flags default to False, so existing invocations are unchanged — the install + validation phases still run by default.
• The login + AI Gateway discovery + save_state happen regardless of the flags, so a consumer passing --skip-install --skip-validation still gets a complete ~/.ucode/state.json (workspace, base URLs, model lists, per-agent config) — only the binary management and test runs are skipped.
• The flags are threaded from configure into configure_workspace_command and guard every install/validate site, so they apply consistently to the --agent, --agents, and interactive paths.

Example:

# Configure routing for one workspace, no binary installs, no validation runs:
ucode configure --workspaces https://my-workspace.cloud.databricks.com \
  --agents claude,codex,pi --skip-install --skip-validation

Testing

• uv run pytest --ignore=tests/test_e2e.py --ignore=tests/test_e2e_tracing.py --ignore=tests/test_e2e_user_agent.py → 673 passed.
• uv run ruff check . → clean.
• Added TestConfigureSkipFlags in tests/test_cli.py:
  • the flags are forwarded from the --agents/--workspaces invocation,
  • --skip-install skips the eager single-agent install (--agent path),
  • --help lists both flags,
  • a behavioral test that configure_workspace_command(..., skip_install=True, skip_validation=True) calls neither install_tool_binary nor validate_all_tools while still running configure_selected_tools, and a paired default-path test asserting both do run without the flags (so the guards aren't always-skip).
• Updated the existing TestConfigureAgentFlag forwarding assertions for the new (default-False) kwargs.

Notes

• Scoped to the requested behavior; no refactors. Existing Rich UI / helper conventions preserved.
• README "Other Commands" table documents both flags.

Pull request overview

Note

Copilot was unable to run its full agentic suite in this review.

Adds opt-in flags to ucode configure to skip agent CLI installation/updates and/or post-configure validation runs, enabling programmatic consumers to perform only workspace auth + AI Gateway routing state setup.

Changes:

• Add --skip-install and --skip-validation flags to the configure CLI and thread them into configure_workspace_command
• Guard install and validation phases in configure_workspace_command with the new flags
• Expand CLI tests and README documentation to cover the new flags and default behavior
