This commit addresses three critical issues from code review:
1. Tool approval enforcement: Tools declaring requires_approval() (shell,
http, file write/patch, build_software) now gate execution. Adds
PendingApproval struct, session-scoped auto-approved tools set, and
approval flow with yes/no/always commands.
2. Tool definition refresh: Tool definitions now refresh each iteration
in both chat and job loops, so newly built tools become visible
immediately within the same session.
3. Worker tool call handling: Changed respond() to respond_with_tools()
when select_tools returns empty, properly executing tool calls instead
of formatting them as text.
Also includes prior work from the plan:
- Wire embeddings provider (OpenAI + NEAR AI) to workspace
- Load workspace system prompt (identity files) into LLM context
- Route heartbeat notifications through channel manager
- Enable auto-context compaction when threshold exceeded
- Refactor to config structs (AgentDeps, WorkerDeps, LlmCallRecord)
- Fix clippy warnings (saturating_sub, too_many_arguments)
