fix(mcp): scrub err.Error() from JSON-RPC error messages (OFFSEC-001)

Replace all three err.Error() leaks in mcp.go with constant strings,
consistent with the same fix applied to 22 other files in PRs #1193/1206/1219/#168.

- Call handler (line ~329): "parse error: " + err.Error() → "parse error"
- dispatchRPC params unmarshal (line ~417): "invalid params: " + err.Error()
  → "invalid parameters"
- dispatchRPC tool call (line ~422): err.Error() → "tool call failed"
  + log.Printf server-side for forensics

Routes protected by WorkspaceAuth (C1) and MCPRateLimiter (C2) — this is
defence-in-depth per OFFSEC-001 / #259.

Tests added:
- TestMCPHandler_Call_MalformedJSON_ReturnsConstantParseError
- TestMCPHandler_dispatchRPC_InvalidParams_ReturnsConstantMessage
- TestMCPHandler_dispatchRPC_UnknownTool_ReturnsConstantMessage
- TestMCPHandler_dispatchRPC_InvalidParams_ArrayInsteadOfObject
