fix(config): bump MODEL_ALIAS_MAP to claude-opus-4-7 (#2733)

* fix(config): bump MODEL_ALIAS_MAP and RUNTIME_PROFILE_MAP to claude-opus-4-7

Opus 4.7 shipped Q1 2026 but MODEL_ALIAS_MAP and RUNTIME_PROFILE_MAP.claude.opus
were still pinned to claude-opus-4-6. Users with resolve_model_ids: true received
stale model IDs in logs and agent-tool calls.

Also adds a resolve_model_ids: true test suite — this path had zero coverage,
which is why the stale ID survived undetected.

Closes #2712

* refactor(config): derive RUNTIME_PROFILE_MAP.claude from MODEL_ALIAS_MAP (coderabbit)

RUNTIME_PROFILE_MAP.claude was duplicating model IDs that MODEL_ALIAS_MAP
already owns. Future model bumps now only require updating MODEL_ALIAS_MAP.
Also fixes stale test assertion (claude-opus-4-6 → claude-opus-4-7).

* fix(tests): update stale claude-opus-4-6 refs to claude-opus-4-7; DRY: derive RUNTIME_PROFILE_MAP.claude from MODEL_ALIAS_MAP

- Update 3 hardcoded `claude-opus-4-6` assertions in tests/issue-2517-runtime-aware-profiles.test.cjs to `claude-opus-4-7`
- Update comment on line 128 that referenced the old model ID
- Replace manual per-tier expansion of RUNTIME_PROFILE_MAP.claude with Object.fromEntries so future alias bumps only require updating MODEL_ALIAS_MAP
