fix(adapter): map persona-friendly slugs (claude-code, anthropic) to registry names

Phase 4 verification surfaced a follow-up edge case the initial fix missed:
the persona env files use friendlier slugs than the registry's canonical names:
  * MODEL_PROVIDER=claude-code  -> anthropic-oauth (Claude Code subscription)
  * MODEL_PROVIDER=anthropic    -> anthropic-api  (direct Anthropic API key)

Without an alias map, a lead workspace's MODEL_PROVIDER=claude-code env
fell through the slug-detection path; when the YAML didn't pin a
provider, the model-prefix matcher saw MODEL=MiniMax-M2.7 and routed the
lead to MiniMax — even though CLAUDE_CODE_OAUTH_TOKEN was clearly the
intended auth path.

Add _PROVIDER_SLUG_ALIASES with the two operator-facing slugs that don't
match registry names verbatim. The alias map is consulted before the
slug-vs-legacy detection, so claude-code now resolves to anthropic-oauth
and the lead boots through OAuth as intended.

Tests
-----
+ test_persona_env_lead_with_minimax_model_routes_via_oauth — lock in
  the alias-map behavior so a future contributor can't silently re-introduce
  the lead-mis-routed-to-MiniMax bug.
+ test_anthropic_alias_resolves_to_anthropic_api — covers the second
  alias path.

Updated test_persona_env_lead_claude_code_resolves_correctly to assert
the new (correct) behavior: provider == 'anthropic-oauth', not None.

Full adapter suite: 78/78 pass.
