Tighten tool parity for agent handoffs and notebook edits

Normalize Agent subagent aliases to Claude Code style built-in names, expose richer handoff metadata, teach ToolSearch to match canonical tool aliases, and polish NotebookEdit so delete does not require source and insert without a target appends cleanly. These are small parity-oriented behavior fixes confined to the tools crate.\n\nConstraint: Must not touch unrelated dirty api files in this worktree\nConstraint: Keep the change limited to rust/crates/tools\nRejected: Rework Agent into a real scheduler | outside this slice and not a small parity polish\nRejected: Add broad new tool surface area | request calls for small real parity improvements only\nConfidence: high\nScope-risk: narrow\nReversibility: clean\nDirective: Keep Agent built-in type normalization aligned with upstream naming aliases before expanding execution semantics\nTested: cargo test -p tools\nNot-tested: integration against a real upstream Claude Code runtime
