docs: rename cisco-docs cross-reference to mcdewey

The sibling docs server was renamed from `mcp-cisco-docs` to `mcdewey`
(generalized from a Cisco-only corpus to a multi-vendor docs library).
Update the prompt-enrichment section to point at the new package name +
its PyPI URL, and adjust the prose to call it "the sibling docs server"
generically rather than "cisco-docs" specifically.

The CHANGELOG entry referencing this project's own pre-rename name
(`mcp-cucm-axl`) is left intact — that's legitimate historical record
of why this project is now `mcaxl`.

 Read-only MCP server for **Cisco Unified Communications Manager (CUCM)** —
 exposes the AXL SOAP API and RisPort70 real-time registration state to
 LLMs for dial-plan analysis, configuration auditing, and impact analysis.
 
 > Tested against CUCM 15.0(1). Should work on any CUCM 12.5+.
 
+## What it looks like
+
+Invoke the `whoami` prompt in any MCP-aware LLM client. With no
+arguments, it defaults to the AXL service account from your `.env`:
+
+> **Account**: `axl-readonly` (applicationuser)
+> **Access control groups**: 1 — `Read-Only-AXL`
+> **Effective roles** (5):
+> - **Standard CCM Admin Users** ← write access
+> - **Standard AXL API Access** ← full read-write AXL
+> - Standard AXL Read Only API Access
+> - Standard Packet Sniffing
+> - Standard RealtimeAndTraceCollection
+>
+> **Finding**: the group `Read-Only-AXL` contains two write-capable
+> roles. The name implies read-only intent but the membership grants
+> full administrative write access. Consider renaming the group OR
+> removing the write-capable roles from its membership.
+
+One tool call. One SQL join across four tables (`applicationuser →
+applicationuserdirgroupmap → dirgroup → functionroledirgroupmap →
+functionrole`). One audit finding with severity and remediation —
+not a raw query result the operator has to interpret on their own.
+That's the shape of every prompt mcaxl ships with: orchestrated
+queries, structured findings, ready-to-act recommendations.
+
+## Scope and complement
+
+`mcaxl` is intentionally narrow — read-only audit of CUCM
+configuration via AXL, with RisPort70 cross-reference for live
+registration state. It does *not* cover operational debugging:
+log collection, packet capture, perfmon counters, service control.
+
+For those, install
+[`@calltelemetry/cisco-cucm-mcp`](https://github.com/calltelemetry/cisco-cucm-mcp)
+alongside this server:
+
+```bash
+claude mcp add cucm-ops -- npx -y @calltelemetry/cisco-cucm-mcp@latest
+```
+
+The two are designed to compose. `mcaxl` answers *"what does the
+config say?"*; `cisco-cucm-mcp` answers *"what's happening right
+now?"*. An LLM session with both connected can produce compound
+findings like *"audit found CSS X has 0 references AND RisPort
+confirms zero phones currently registered against any device pool
+that inherits it → confirmed safe to delete."*
+
