Fix all gaps identified by spec review against docs/specs/coding-agent-loop-spec.md:
- Replace placeholder system prompts with substantial provider-aligned prompts
for OpenAI (codex-rs style), Anthropic (Claude Code style), and Gemini
(gemini-cli style) covering identity, tool usage, and coding best practices
- Fix ExecutionEnvironment trait: add offset/limit to read_file, depth to
list_directory, path to glob, remove separate args from exec_command
- LocalEnv: use /bin/bash -c, spawn process groups with setsid, SIGTERM to
-pid, use ripgrep with grep fallback, add env var safelist
- Add environment context block with <environment> XML tags including git
branch, date, model, and knowledge cutoff fields
- Capture git context snapshot (branch, status, recent commits) on init
- Add user_instructions to SessionConfig, appended as final prompt layer
- Emit AssistantTextStart before LLM calls, SESSION_END on abort path
- Fix truncation messages to match spec wording exactly
- Implement provider_options() for all profiles (reasoning, beta headers,
safety settings)
- Add Gemini-specific tools: read_many_files, list_dir, web_search, web_fetch
- Wire spawn_agent max_turns parameter
- Fall back to working_dir for project doc discovery outside git repos
All 188 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.
