- Extract shared test infrastructure (MockExecutionEnvironment, TestProfile,
MockLlmProvider) replacing 11 duplicate mock implementations across tests
- Deduplicate tool execution logic between sequential and parallel paths
- Narrow ProviderProfile trait from 14 to 7 required methods via
ProfileCapabilities struct and default implementations
- Replace stringly-typed HashMap event data with typed EventData enum
- Extract shared assemble_system_prompt helper and register_subagent_tools
default method, eliminating copy-paste across all 3 profiles
- Replace fragile shell-based glob with glob crate, fix rg detection
- Add delete_file to ExecutionEnvironment, wire git context into env block
- Remove dead code (AgentError::Io, count_turns, trivial derived-trait tests)
- Use match-based lookups in truncation instead of per-call HashMap allocation
Net reduction: -1,401 lines across 20 files. All 180 tests pass.

Close spec compliance gaps:
- Add user_instructions to SessionConfig and ProviderProfile trait (spec Section 6.1 layer 5)
- Populate EnvContext with git branch, date, model name during Session::initialize()
- Expand all three profile system prompts with identity, tool guidance, coding practices
- Implement provider_options: Anthropic beta headers, OpenAI reasoning effort, Gemini safety settings
- Add register_subagent_tools() to all profiles for spawn_agent/send_input/wait/close_agent
- Add list_dir tool to Gemini profile (spec Section 3.6)
- Add chrono dependency for date formatting
20 new tests (170 → 190), all passing.

- Abort now transitions to CLOSED state and returns Err(Aborted)
- Closed sessions no longer emit SessionStart before rejecting input
- Add set_reasoning_effort() for mid-session reasoning effort changes
- Fix spawn_agent truncation limit from 30k to spec-required 20k
- Add JSON Schema validation of tool arguments before execution

Replace all stub tools in profiles with real make_*_tool() factories,
wire up project docs discovery in session, add missing events
(SessionStart, SteeringInjected, Error), enrich environment context
block, fix per-tool truncation modes, improve loop detection to check
all groups, add SIGTERM-before-SIGKILL on timeout, and update subagent
with SubAgentResult struct.
