TinyAgent provider guard removal + OpenAI-compatible base_url path

Summary

Unblocked non-openrouter: models when using OpenRouterModel(base_url=...).

• Removed hard provider guard from agent model construction.
• Removed hard provider guard from compaction model construction.
• Added API key fallback behavior for non-openrouter providers:
  • use provider-specific env key first
  • fallback to OPENAI_API_KEY
• Added tests for base URL propagation, non-openrouter provider support, and normalized usage payload parsing (cacheRead).
• Removed dead shim module src/tunacode/core/tinyagent/openrouter_usage.py.

Key changes

• src/tunacode/core/agents/agent_components/agent_config.py
  • _build_tinyagent_model() now accepts any provider id parsed from provider:model.
  • _build_api_key_resolver() validates env mapping type and adds OPENAI_API_KEY fallback.
• src/tunacode/core/compaction/controller.py
  • _build_model() no longer blocks non-openrouter providers.
  • _resolve_api_key() now mirrors provider-first then OPENAI_API_KEY fallback.
• tests/unit/core/test_tinyagent_openrouter_model_config.py (new)
  • Base URL propagation test.
  • Non-openrouter provider with base URL test.
  • API key fallback tests for agent and compaction paths.
• tests/unit/core/test_openrouter_usage_metrics.py
  • Added normalized usage coverage for top-level cacheRead key.
• tests/unit/core/test_compaction_controller_outcomes.py
  • Updated capability test to expect missing provider API key behavior for non-openrouter provider.
