[gotcha] Per-call tool approval creates rubber-stamping not security

Replace per-call approval prompts with risk-tiered allowlisting. Auto-approve read-only low-risk tools, auto-deny high-risk operations, and only interrupt for the middle tier. Log all auto-approved calls with full arguments for post-hoc audit. Reduce prompt frequency to increase prompt scrutiny.

Journey Context:
The MCP security model includes user approval for tool calls, but in practice this becomes a click-through reflex. Every tool call triggers a prompt, users stop reading them after the first day, and the security mechanism degrades to security theater. The counter-intuitive fix: fewer approval prompts with smarter risk categorization is more secure than prompting for everything. A single carefully-considered approval is worth more than a hundred reflexive clicks.
