Change local-runner default mode to current user environment

[Copilot]

Why

PR #856 changed local-runner to create a temporary venv by default, breaking the original behavior where it ran in the current user environment. This restores that behavior as the default while preserving the new modes.

How

• Added 'current' mode to run in user's existing environment (no venv creation)
• Changed default from 'env' to 'current'
• Updated CLI option to --mode [current|env|container] with explicit elif branches for each mode
• Added test_local_runner_mode_options to verify all three modes

Tests

• All 8 existing tests pass with new default
• New test validates:
  • Default mode skips venv creation
  • --mode env creates venv and installs requirements
  • --mode current explicitly skips venv creation

Notes

• Only affects local-runner command; local-test and local-grpc unchanged per issue scope
